Hi Cemal.

>>I have two combos in a form.
From the first you can select the customer from his id.
From the second you can select the custtomer from his name. <<

Instead of the two combo boxes why not use one list box with 2 columns? Set the RowSourceType to 6-Fields and the RowSource to Customer.ID, Name. Set ColumnCount to 2, ColumnWidths to what is appropriate.
