I m trying to have a check box bring up a message box when the accompanied text box is empty. Both the chack and text box are on the same form. I wrote a similar one that has the chack box on one form and the text box on a sub form. That one works great but this bugger is getting the best of me.
I know it's probably something really simple. Here is what I have so far;
Private Sub Termed_AfterUpdate()
If (IsNull(Me![Termed Date])) Then
err_msg = MsgBox("Please Enter Termed Date", vbOKOnly, "Date Error")
