@Serenna Brookman‚ - I pieced together the Excel macro from several online tutorials. For all [ INSERT COLUMN NUMBER HERE ] tags within the code, you'll need to provide the column numbers for your multi-select fields. You can add/remove OR statements within the macro to match your spreadsheet. Here's the code:
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 = [ INSERT COLUMN NUMBER HERE ] _
Or Target.Column = [ INSERT COLUMN NUMBER HERE ] _
Or Target.Column = [ INSERT COLUMN NUMBER HERE ] _
Or Target.Column = [ INSERT COLUMN NUMBER HERE ] _
Or Target.Column = [ INSERT COLUMN NUMBER HERE ] Then
If oldVal = "" Then
'do nothing
Else
If newVal = "" Then
'do nothing
Else
Target.Value = oldVal _
& ", " & newVal
' NOTE: you can use a line break,
' instead of a comma
' Target.Value = oldVal _
' & Chr(10) & newVal
End If
End If
End If
End If
exitHandler:
Application.EnableEvents = True
End Sub
