Excel/mac 2011 decreasing list VBA

Question
Hi,

I'm trying to write a VBA code for a validation list in excel 2011 for mac that removes an item in the list once it been selected so it cannot be selected in 2 cells at once. I'm new to VBA and I found a code online for this exact function but it wont work and I cant troubleshoot it. Can you tell me where my error is? This is the code I used:


Private Sub Worksheet_Change(ByVal Target As Range)

Dim strVal As String

Dim strEntry As String



   On Error Resume Next

       strVal = Target.Validation.Formula1

         If Not strVal = vbNullString Then

         strEntry = Target

         Application.EnableEvents = False

         With Sheet1.Range("Mylist")

         .Replace What:=strEntry, Replacement:="", _
         LookAt:=xlWhole, SearchOrder:=xlByRows, MatchCase:=False

         .Sort Key1:=.Range("A1"), Order1:=xlAscending, Header:=xlNo, _
         OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom

         .Range("A1", .Range("A65536").End(xlUp)).Name = "Mylist"

         End With

         End If

       Application.EnableEvents = True

   On Error GoTo 0

End Sub

I followed the directions(http://sourcedaddy.com/ms-excel/provide-decreasing-data-validation-lists.html) that accompanied the formula but nothing changed, the list works but the items don't disappear once selected.

Thanks,
Jeff

Answer
Jeff -

The code works perfectly on my computer, so I'm pretty sure I know what the problem is. I have a PC. The VBA code has probably been written for the PC. You have a Mac - Mac Excel 2011 does not support scripting runtime objects, you have to create your own classes.

You can create your own Module and build your own classes. Unfortunately, although I understand the problem I can't help with the solution. If you don't know how to do build a Class file, that's OK - there are a number of examples and class library texts (too large to replicate here) that you can find.

Wish I could be more help - Andrea
