Variable Help Needed!!!!! Please!!!

Hello. I am creating a thing that will help me in creating web pages. Sort of like an alternative to Frontpage or Dreamweaver, except not nearly so complex. Right now I am working on the form part. I have to variables, like $text_box_1 and $text_times. $text_times is set to 1, so I want to have $text_box_$text_times be the same as $text_box_1. How can I do this? My source is attached. Line 104 is the problem. PLEASE HELP ME!!!! Please. Thank you, world, in advance. Please? The form.php3 is at www.st-thomas-aquinas.com/new/form.php3. Thank you. Please remember this is a work in progress, and nothing works right. Any other advice would also be greatly appreciated. Thank you, again.
