Creating a Search Form

Im not sure i understand, for demonstration purposes im going to use Microsft Access as my B/E , the customer data is all stored on one table, so i assign Custom ACC number as a combo box? or a text box?

and then add 3 blank list boxes? for the Customer Main Address, Site Address, Acc Balance.? then when the combo box lists all of the ACC Numbers ( i would ideally like it to both drop down and search) is clicked it fills outh the list boxes?

regards
