thanks in advance slavisa I'm a little confused as to exactly what it is you're trying to accomplish here, but in order to have a combo box that retrieves the course descriptions: 1) Create a form using the table Course Numbers as the Record Source.2) Goto the Field List and drag the Course Description field onto the form 3) Place a combo box on the form 4) Select "Find a record on my form based on the value I've selected..." 5) Next 6) Select Course Number 7) Next 8) Size the Combo box column 9) Next 10) Name the combo box 11) Finish Now the user can use the dropdowwn arrow of thecombo box to retrieve the course description or simply start typing the course number in and the combo box will start to autocomplete the entry.
