I have two comobboxes CB3 and CB2. What I want to do is when CB2 is blank and CB3 is clicked to have an error msgbox that says please select an item in CB2 and at the same time trigger CB2's DROPBUTTONCLICK EVENT. Does anyone know how to code this? Thanks!
If ComboBox2.Value = "" Then
MsgBox ("Please select a CB2")
End if
