Hi

If Len(Trim(Nz(MyCombo,"")&"")) = 0 Then
cmdMyButton.enabled = False
Else
cmdMyButtom.Enabled = True
End If

you need code like this in the on open event of the form, and in the after update event of the combo box

you need to use your own control names of course in place of the "my" names I have used

Dosen´t work.
I think that code works because it dosen´t throw any error, but button value isn´t enabled=false in conditions.

Hi

Post your code, and tell me what happens when you step through the code using the debugger, ie which of the two options (true or false) are executed

Hi

Yes, so do you want me to be a mind reader, please post your code (including the event header) and answer the question ref stepping through the code using the debugger

No it´s work, thanks.
Btw that combo box event must be on current.
