Firefox not showing database results

My website is a standard .asp setup using an access database on the server. All works fine with IE and loads of other browsers but I have a problem with Firefox and Netscape. Both of these browsers will display the menu screen or for that matter any screen which has static pictures,text and buttons on it. But will not display the database results when a search button is pressed!
Am I missing a trick?

 

Which program did you use to set up your website? I know nothing much about creating websites, but if you created it with Front Page, it will work with with IE, but not too well with other programs.
