I'm sorry, this depth of access is confusing for me. I right click and get Build...
I click on that then have a choice of expression, macro or code builder. I choose code builder, then typed in Me.PartNumber=Me.ComboBox.Column(1).
I should be putting the combo box name, not "ComboBox", right, because I'm getting an error. Should the Item number also be a combo box? The the string should read Me.PartNumber=Me.ItemNumber.Column(1).
I'm I way off here? Sorry to be so slow with this.
