Thanks Andy!

I haven't tried your code direction yet, but will likely give it a shot with another form with the same desired functionality. I stumbled on something in a search that I modified as follows and it seems to work so far, but your code looks more straightforward. If you happen to see this post and have an opinion if I'm breaking convention or was just plain lucky I'd be very interested. There seemed to be some mystery with the multiselectmulti option for listbox. I'm trying to learn by fire some integrity to what I'm building!

Again appreciate the info. Take care.

Private Sub frmBizContext_Initialize()
txtBizContextOther.Enabled = False
txtBizContextOther.Visible = False
txtBizContextOther.Value = ""
End Sub

Private Sub listExpTopics_Change()
If listExpTopics.Selected(14) = False Then
txtBizContextOther.Value = ""
txtBizContextOther.Enabled = False
txtBizContextOther.Visible = False
Else
txtBizContextOther.Enabled = True
txtBizContextOther.Visible = True
End If
End Sub
