Hello,

I need to develop an UDF for checking a cell value against several possible entries to check if the cell is equal to any of those values or not. I know how to do the check (I am thinking to assign the entries to a scripting dictionary and do a dic.exists function). But writing the function in a way that can accept multiple optional entries in not clear for me. The example in EXCEL functions is CONCATENATE( text1, [ text2, ... text_n ] ). My function for specific optional entries is as follow:

Code: 
Function IfAmong(TextToCheck As String, Text1 As String, Optional Text2 As String, Optional Text3 As String, Optional Text4 As String, Optional Text5 As String, Optional text6 As String) As Boolean    Dim dd As New Scripting.Dictionary
    dd.CompareMode = TextCompare
    dd.Add Text1, dd.Count
    If Text2 <> "" Then dd.Add Text2, dd.Count
    If Text3 <> "" Then dd.Add Text3, dd.Count
    If Text4 <> "" Then dd.Add Text4, dd.Count
    If Text5 <> "" Then dd.Add Text5, dd.Count
    If text6 <> "" Then dd.Add text6, dd.Count
    IfAmong = dd.Exists(TextToCheck)
    dd.RemoveAll
End Function

I want to make it dynamic for number of optional entries (As said like concatenate). and also if possible make the checking of entries automatic through a loop.

Code: 
for i =2 to Ubound(text(i))
     if text(i) <>"" then..........
next

I was not able to do that as well

Thanks and regards,
M

Hello,

I found the solution with help of stackoverflow fellas. Here is the reply.

Use the <code style="margin: 0px; padding: 1px 5px; border: 0px; font-variant-numeric: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap; color: rgb(36, 39, 41);">ParamArray</code>. The <code style="margin: 0px; padding: 1px 5px; border: 0px; font-variant-numeric: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap; color: rgb(36, 39, 41);">ParamArray</code> must always be the last thing to be declared and must be of the type <code style="margin: 0px; padding: 1px 5px; border: 0px; font-variant-numeric: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap; color: rgb(36, 39, 41);">Variant</code>. It will allow you to enter as many variables as you like without having to define each one of them.

It is not so good routine as will turn error if duplicated value entered! you can find a more simple suggestion on link above.
