I have a site I created for real estate. The user can search for listings by any, or all, of the following variables... county, property type, square footage range and price range. My search works great using drop down lists that are populated by the database. What I want to do is use menus so the user could select say several counties and all listings that matched the other criteria within those three counties would show in the results. Unfortunately when I try to do this it only comes back with the last item selected. I have been told I need to use arrays but don't understand how to use them. I don't know enough to hand code them and have always used Dreamweaver extensions. Any help would be greatly appreciated as I have been working on this for months now. Thanks, Mark
