forms

Hello. I have a form page with drop down select lists. The data returned from the form are displayed below the form. Originally i had this document in frames using perl/cgi, and once the results for the query were returned in the lower frame, the upper frames' drop down boxes were unchanged. Now, the drop down boxes are reset after every query becuase the entire page is returned. My question is: Is there some way of having the drop down selections "remembered" from the previous queries? -thanks in advance
