Hello!

I'm still a newbie to the VBA and Userform usage.
I have developed a Userform that will input the information from the Userform into the cells I have designated. I'm still trying to understand Arrays. But I have it setup in array for Vendor and Probe Type:

VBA Code:
Private Sub VendorBox_DropButtonClick()
'Add a NEW Vendor into Array below using , and " marks surrounding name
 vendor = Array("Metasystems", "Cytocell", "Vysis")

 FISHValform.VendorBox.List = vendor


End Sub
VBA Code:
Private Sub VendorBox_AfterUpdate()


Select Case VendorBox.Value
'Add NEW Section entered above as a NEW Case down below following the same format. List the Reagents for that section

 Case "Vysis":

  probetype = Array("Dual Color, Dual Fusion", "Breakapart")
  
 Case "Cytocell":

 probetype = Array("Dual Color, Dual Fusion", "Deletion Probe", "Breakapart", "Alpha Satellite/Centromere")
 
 Case "Metasystems":

 probetype = Array("Dual Color, Dual Fusion", "Deletion Probe", "Breakapart", "Alpha Satellite/Centromere")
  
End Select
   

ComboBox2.List = probetype

  

End Sub


The issues I am trying to figure out are:
1) Since all 3 vendors have the same probe types, how do I setup the "Probe" Combox array in such a way as to differentiate between each Vendor? Or is there an easier way to do that?

2) Each "Probe" has its own different "Probe Regions" that can fill 1-3 cells. How do I get it to auto-populate these based on the Probe selected? More arrays? The list of probes is decently long to want to type each of these up :S (but I can do it, this list will not grow).

Hi,

Not sure I have fully understood but if you want to select different lists for each probe based on vendor selection, include the probe arrays in your select case statement

Untested but something like this maybe?

Code:
Private Sub VendorBox_Change()
    Dim probetype   As Variant, probe As Variant
 
    Select Case VendorBox.Value
        Case "Vysis":
         
            probetype = Array("Dual Color, Dual Fusion", "Breakapart")
            probe = Array("Probe7", "Probe8", "Probe9")
         
        Case "Cytocell":
         
            probetype = Array("Dual Color, Dual Fusion", "Deletion Probe", "Breakapart", "Alpha Satellite/Centromere")
            probe = Array("Probe4", "Probe5", "Probe6")
         
        Case "Metasystems":
         
            probetype = Array("Dual Color, Dual Fusion", "Deletion Probe", "Breakapart", "Alpha Satellite/Centromere")
            probe = Array("Probe1", "Probe2", "Probe3")
         
    End Select
 
    With Me.cboProbeType
        .Clear
        If IsArray(probetype) Then .List = probetype
    End With
 
    With Me.cboProbe
        .Clear
        If IsArray(probe) Then .List = probe
    End With
 
End Sub

Personally, rather than hard code the arrays I would create tables & have the code read from them. Using tables makes code shorter & easier for you to maintain the lists.

Also, suggest that you consider
If you are new to userforms then maybe you will find this article of some help: Introduction to UserForms

Hope Helpful

Using ranges as Dave suggests gives you flexibility:
E.g.

Lookups
Cells with Data Validation
CellAllowCriteria
G4:I7List=$D$4:$D$7
O3:S3List=$E$4:$E$8
O4:S6List=$B$4:$B$13



The associated code for the data formcan include:
VBA Code:
Option Explicit

Private Sub UserForm_Initialize()
    Dim ws As Worksheet
    Set ws = Sheets("Lookups")
   
    Me.cboVendor.List = ws.Range("Range_Vendors").Value  '  C4:C6 -  Populate vendorscombo
    Me.cboVendor.ListIndex = 0
   
    Me.cboProbeType.List = getVendorProbeTypes(Me.cboVendor.Value)  ' populate probetype combo
    Me.cboProbeType.ListIndex = 0
   
    Me.cboProbe.List = getVendorProbe(Me.cboVendor.Value) ' populate probe combo
    Me.cboProbe.ListIndex = 0
End Sub


Private Sub cboProbe_Change()
    Dim arr As Variant
    arr = getRegions(Me.cboProbe.Value) ' populate region text boxes
    Me.txtRegion1 = arr(0)
    Me.txtRegion2 = arr(1)
    Me.txtRegion3 = arr(2)
End Sub

Private Sub cboVendor_Change()
    Me.cboProbeType.List = getVendorProbeTypes(Me.cboVendor.Value)  ' populate probe types
    Me.cboProbeType.ListIndex = 0
   
    Me.cboProbe.List = getVendorProbe(Me.cboVendor.Value)  ' populate probe
    Me.cboProbe.ListIndex = 0
End Sub



This code goes in a standard module:
VBA Code:
Option Explicit

Function getRegions(sProbe As String) As Variant
   
    Dim R As Range, j As Integer, ws As Worksheet, arr() As String
    Set ws = Sheets("Lookups")
    ReDim arr(0 To 2)
   
    Set R = ws.Range("Range_Probes").Find(sProbe)  ' P3:T3 .. expand as needed
    If Not R Is Nothing Then
        For j = 0 To 2
            arr(j) = R.Offset(j + 1).Value
        Next j
    End If
    getRegions = arr
End Function

Function getVendorProbeTypes(sVendor As String) As Variant
    Dim R As Range, j As Integer, ws As Worksheet, arr() As String, cnt As Integer
    Set ws = Sheets("Lookups")
    ReDim arr(0 To 0)
   
    Set R = ws.Range("Range_Vendor_Probetypes").Find(sVendor) ' G3:I3
    If Not R Is Nothing Then
        cnt = IIf(R.Offset(1).Value <> "", R.End(xlDown).Row - R.Row, 0)
        If cnt <= 1 Then ' only one value, or no values in column
            arr(0) = R.Offset(1)
        Else
            ReDim arr(0 To cnt - 1)
            For j = 0 To cnt - 1
                arr(j) = R.Offset(j + 1).Value
            Next j
        End If
    End If
    getVendorProbeTypes = arr
   
End Function

Function getVendorProbe(sVendor As String) As Variant
    Dim R As Range, j As Integer, ws As Worksheet, arr() As String, cnt As Integer
    Set ws = Sheets("Lookups")
    ReDim arr(0 To 0)
   
    Set R = ws.Range("Range_Vendor_Probes").Find(sVendor) ' K3:M3
    If Not R Is Nothing Then
        cnt = IIf(R.Offset(1).Value <> "", R.End(xlDown).Row - R.Row, 0)
        If cnt <= 1 Then ' only one value, or no values in column
            arr(0) = R.Offset(1)
        Else
            ReDim arr(0 To cnt - 1)
            For j = 0 To cnt - 1
                arr(j) = R.Offset(j + 1).Value
            Next j
        End If
    End If
    getVendorProbe = arr
   
End Function

I didn't use listObjects (tables) which I would normally do, but I think you already have enough to digest.

Solution
In the listings for post #3 my assumptions are that as the vendor is changed, the "probe types" and "probes" comboboxes are updated. Also, when the "probe" combobox"selection changes, the 3 textboxes for "probe regions" will get updtaed.

Also a correction to the inline code comments:
Set R = ws.Range("Range_Probes").Find(sProbe) ' P3:T3 .. expand as needed
should read
Set R = ws.Range("Range_Probes").Find(sProbe) ' O3:S3 .. expand as needed

I inserted or deleted a column but didn't update the comment. The code will stiill work of course.
It's good to use named ranges rather than explicit cell references !!.

Thank you for your help! :)

I am reproducing your table/sheet/codes exactly as you presented them, but I am running into an error. I am getting a "Compile Error: Method or data member not found" for ".cboVendor". I've made sure I've renamed all my userform boxes and sheets according to your example and copied naming all the ranges in the exact format as you have them. Unsure why this error is happening :S (double checked spelling, double checked that "Vendor" is the name of the combobox, and that it is in fact a combobox, etc)

(Doing this as a copy/practice worksheet(s) before I change the info of the table to be the exact information that I need for the official workbook)

The solution as presented is testing and working, so there's defiitely some disconnect between what you typed and the control names on your form.
When in the editor, in one of the subs in the userform, type me. and the autocomplete should bring up a list of control names on the form. The list should include :
cboVendor
cboProbeType
cboProbe
txtRegion1
etc etc

if those don't show up on autocomplete then the controls are probably incorrectly named
confirm what controls you see when typing me.

I am now getting an error involving:

VBA Code:
Me.cboProbeType.List = getVendorProbeTypes(Me.cboVendor.Value)  ' populate probe types

where the error is 1004 Method 'Range' of object '_Worksheet' failed

Runtime error 1004: Method 'Range' of object '_Worksheet' failed​

This error suggests you have incorrectly named or omitted one of the named ranges.
Firstly, confirm that the worksheet name is Lookups
Secondly, at a minimum you should have the named ranges shown here - (Press Control and F3 to bring up the name manager):
