forms and databases usinh PHP

Hello, Has anyone run into problems using PHP to access a database (MySQL) and build a form. I am trying to build a form that contains anywhere from 10 to 20 tables. Each table will contain drop down menus, text boxes and text areas. As you may envision, this form can be quite lengthy. I populate the form by creating a loop and accessing the MySQL database. Each iteration returns data (24 fields) from a record in my Database table). My problem is that after loading the page, my browser appears to lock up and any attempt to run other programs gives me a Windows Low Memory error (and that I should close other programs). Note: Third may not be a PHP problem but as I am unsure, I have to start somewhere. Note2: I have already queried the HTML newsgroup and the feedback I received was that large forms should not cause this problem. Thanks, Don
