Action based on Combo Box Selection

[Guest]

I have a TranType combo box with 2 columns. Column 1 is the TranID, and
column 2 is the TranName. If a user selects "Revenue" in the combo box
(which is TranID 1), then it enables the Rate and Members controls. This
code isn't working. Can anyone debug?


Private Sub TranType_AfterUpdate()

If Me!TranType.Column(1) = 1 Then
Me.Rate.Enabled = True
Me.Members.Enabled = True
End If

End Sub

The Column index is zero based.

Your code is incomplete in that it should probably disable
the controls when a different trantype is selected.

Try this:
Me.Rate.Enabled = (Me!TranType.Column(0) = 1)
Me.Members.Enabled = (Me!TranType.Column(0) = 1)

Note that if the combo box's BoundColumn property is set to
1, the combo box's Value will be the trantype value
(regardless of the column displayed in it text portion.
This means that you don't need to use the Column(0) property
at all:
Me.Rate.Enabled = (Me!TranType) = 1)
Me.Members.Enabled = (Me!TranType = 1)
