Hi to everyone,
I am new to the forum and to the vba code. I am creating an excel workbook which would automate certain type of routinary calculations.
So far all I wanna do is to add to my workbook a cell conditional value according to a number which I have in a cell (let's say C10).
I created a peice of script which has to delete or insert values and formulas according to the value in cell C12


Code: 
Private Sub Worksheet_Change(ByVal Target As Range)
    Application.ScreenUpdating = False
    NmrStd = Sheets("Step 1").Range("C10").Value
    Select Case NmrStd
    Case Is = 2
        Selection.Range("D17 : I18").ClearContents
        [COLOR=#000000][FONT=inherit]Worksheets[/FONT][/COLOR][COLOR=#666600][FONT=inherit]([/FONT][/COLOR][COLOR=#008800][FONT=inherit]"Step 1"[/FONT][/COLOR][COLOR=#666600][FONT=inherit]).[/FONT][/COLOR][COLOR=#000000][FONT=inherit]Range[/FONT][/COLOR][COLOR=#666600][FONT=inherit]([/FONT][/COLOR][COLOR=#008800][FONT=inherit]"K20"[/FONT][/COLOR][COLOR=#666600][FONT=inherit]).[/FONT][/COLOR][COLOR=#000000][FONT=inherit]Formula[/FONT][/COLOR][COLOR=#000000][FONT=inherit] [/FONT][/COLOR][COLOR=#666600][FONT=inherit]=[/FONT][/COLOR][COLOR=#000000][FONT=inherit] [/FONT][/COLOR][COLOR=#008800][FONT=inherit]"=AVERAGE(I15 : I16)"[/FONT][/COLOR]

    Case Is = 4
     Selection.Range("D17 : E18").ClearContents

It was probably recursive events causing the crash

This will stop it

Application.EnableEvents

This code will work

Is the worksheet "Step 1" if so they might be redundant references

Code: 
Private Sub Worksheet_Change(ByVal Target As Range)
    
    On Error Resume Next
    ' the range C10 on the current sheet has changed
    If Intersect(Target, Range("C10")) Is Nothing Then
      Exit Sub
    End If
    'stop the worksheet change event triggering because of changes caused by the code in the work sheet change event
    Application.EnableEvents = False
    Application.ScreenUpdating = False
    
    NmrStd = Target.Value
    
    Select Case NmrStd
        Case Is = 2
            Selection.Range("D17 : I18").ClearContents
            Worksheets("Step 1").Range("K20").Formula = "=AVERAGE(I15 : I16)"
    
        Case Is = 4
         Selection.Range("D17 : E18").ClearContents
         Worksheets("Step 1").Range("D17").Value = "STD1"
         Worksheets("Step 1").Range("D18").Value = "STD2"
         Worksheets("Step 1").Range("I17").Formula = "=E17/(F17*G17*H17)"
         Worksheets("Step 1").Range("I18").Formula = "=E18/(F18*G18*H18)"
         Worksheets("Step 1").Range("G17").Formula = "=SE(E17>0;CERCA.VERT(F2;Prodotti!A3:S37;19;FALSO);"")"
         Worksheets("Step 1").Range("G18").Formula = "=SE(E17>0;CERCA.VERT(F2;Prodotti!A3:S37;19;FALSO);"")"
         Worksheets("Step 1").Range("K20").Formula = "=AVERAGE(I15 : I18)"
    
    End Select
Application.ScreenUpdating = True
're-enable events
Application.EnableEvents = True

End Sub

CharlesChuckieCharles it works simply wonderfully. I have one more question.

I wanted to add another part to your code which allows to hide or unhide a worksheet called "Step 2" but it does not work. How can we sort it out this.

Code: 
Private Sub Worksheet_Change(ByVal Target As Range)
    
    On Error Resume Next
    ' the range C10 on the current sheet has changed
    If Intersect(Target, Range("C9")) Is Nothing Then
      Exit Sub
    End If
    'stop the worksheet change event triggering because of changes caused by the code in the work sheet change event
    Application.EnableEvents = False
    Application.ScreenUpdating = False
    
    NmrStd = Target.Value
    
    Select Case NmrStd
        Case Is = 2
            Selection.Range("D17 : I18").ClearContents
            Worksheets("Step 1").Range("K20").Formula = "=AVERAGE(I15 : I16)"
    
        Case Is = 4
         Selection.Range("D17 : E18").ClearContents
         Worksheets("Step 1").Range("D17").Value = "STD1"
         Worksheets("Step 1").Range("D18").Value = "STD2"
         Worksheets("Step 1").Range("I17").Formula = "=E17/(F17*G17*H17)"
         Worksheets("Step 1").Range("I18").Formula = "=E18/(F18*G18*H18)"
         Worksheets("Step 1").Range("G17").Formula = "=SE(E17>0;CERCA.VERT(F2;Prodotti!A3:S37;19;FALSO);"")"
         Worksheets("Step 1").Range("G18").Formula = "=SE(E17>0;CERCA.VERT(F2;Prodotti!A3:S37;19;FALSO);"")"
         Worksheets("Step 1").Range("K20").Formula = "=AVERAGE(I15 : I18)"
    
    End Select


[COLOR=#0000ff]cell = Sheets("Step 1").Range("C11").Value[/COLOR]
[COLOR=#0000ff]
[/COLOR]
[COLOR=#0000ff]If cell = 2 Then[/COLOR]
[COLOR=#0000ff]
[/COLOR]
[COLOR=#0000ff]Worksheets("Step 2").Visible = xlVisible[/COLOR]
[COLOR=#0000ff]
[/COLOR]
[COLOR=#0000ff]Else[/COLOR]
[COLOR=#0000ff]
[/COLOR]
[COLOR=#0000ff]Worksheets("Step 2").Visible = xlVeryHidden[/COLOR]
[COLOR=#0000ff]End If[/COLOR]


Application.ScreenUpdating = True
're-enable events
Application.EnableEvents = True

Keep in mind that must remain protect by password (of course excluding cells needed to insert numbers)
Thanks a lot

If you're using theVBA to protect the sheets then use

ActiveWorkbook.Sheets("Sheet1").Protect "google", True, True, True, True

where the forth TRUE is :

UserInterfaceOnly : Optional Variant True to protect the user interface, but not macros. If this argument is omitted, protection applies both to macros and to the user interface.

(Worksheets is'nt a thing in Excel it's Sheets or WorkSheet)

If Sheets("Step 1").Range("C11").Value= 2 Then
sheets("Step 2").Visible = xlVisible
Else
sheets("Step 2").Visible = xlVeryHidden
End If

Thanks a lot for your reply. As a new user, were I put this piece of code? Workbook opening section?

Code: 
[COLOR=#333333]ActiveWorkbook.Sheets("Sheet1").Protect "google", True, True, True, True [/COLOR]

THis normally an action you'd carry out when saving, and it would normally complement an unprotect action when opening or doing a specific action, so where you place this code is down to how you see your solution working from a users point of view
