multiple choice data validation

[Guest]

hi gurus -
i want to have a data validation where you can select multiple items from a
drop-down list, where the multiple choices compile in the one cell.

from someone previously asking the same thing, I went to Debra Dalgleish's
great site & found a sample worksheet about just that, per Max's suggestion:
"Try Debra's sample file at:
http://www.contextures.com/excelfiles.html
Under Data Validation, look for:
DV0017 - Select Multiple Items from Dropdown List"

I pasted the code from that tab into the code view of my own tab. I only
had to tweak Debra's coding a little bit to get it to work for my purposes,
including adding multiple target columns, which I needed. I had this working
just fine, but then when I sent the xls to a co-worker who is the one needing
to use it, it didn't work. So I sent it to another co-worker with whom I
would try to troubleshoot it, and strangely it then worked for the 2nd
co-worker, but not for me.

So I retraced my steps and would try to troubleshoot my own xls. But when I
went back and downloaded Debra's sample file again, now HERS doesn't even
work for me! What could I be doing wrong? I have macros enabled (in fact
security set to low so i don't have to). Are there any other settings that
would make this not work? I haven't changed anything that I know of since
the file was working for me (my own) just a few days ago. Very strange...

Thanks!!

oh - in case it helps, here is the code currently on my tab with the
validations. I don't know much about code, but only tinkered with it a
little. It was working fine until just today. Anyone see anything in this
that would make it unstable?

here's the code (from 'view code' after right-clicking the sheet tab):

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
If Target.Count > 1 Then GoTo exitHandler

On Error Resume Next
Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitHandler

If rngDV Is Nothing Then GoTo exitHandler

If Intersect(Target, rngDV) Is Nothing Then
'do nothing
Else
Application.EnableEvents = False
newVal = Target.Value
Application.Undo
oldVal = Target.Value
Target.Value = newVal
If Target.Column = 8 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 9 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 11 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 12 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 13 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 14 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 15 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
If Target.Column = 16 Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ";" & newVal
End If
End If
End If
End If

exitHandler:
Application.EnableEvents = True
End Sub

Nothing jumps out, but a) simplify it (see below), and b) put a break in to
see whatr happens.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
If Target.Count > 1 Then GoTo exitHandler

On Error Resume Next
Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitHandler

If rngDV Is Nothing Then GoTo exitHandler

If Not Intersect(Target, rngDV) Is Nothing Then
Application.EnableEvents = False
newVal = Target.Value
Application.Undo
oldVal = Target.Value
Target.Value = newVal
If Target.Column >= 8 And Target.Column <= 16 Then
If oldVal <> "" And newVal <> "" Then
Target.Value = oldVal & ";" & newVal
End If
End If
End If

exitHandler:
Application.EnableEvents = True
End Sub

Thanks Bob
But what do you mean by "put a break in"?

 

[Guest]

Well - it's working again now! Thanks Bob!
Hopefully this time it will stay working....

 

[Bob Phillips]

I mean put a break in a line of code, select it in the VBIDE and F8(. Then
when it is run, it will stop and you can step through, F8, and see what
happens.
