DataAssist Search / Result / Clear Result

First of all I'm probably doing something stupid to make this not work, but I need some help.

I've set up my search form to search a certain table in my database. My results page comes up with the certain number of results on the page. I have a button to go back to the page that lists all of the items in my table. When you click that button, it then goes to that page but keeps the search results. I'd hit f5 and it wouldn't change, then I would clear cache and cookies in Firefox (newest version and IE7) and it would show up what I wanted.

Well I then enabled a clear session variable (using Cookie Toolkit) and set a cookie for -20 days on page submit (from my results page). Then when you clicked the link it would take you to the same results you looked for, but this time if you hit f5 it would refresh to every listing in my table (what I wanted).

What am I doing wrong? I need this to work on the first time when someone wants to list all of the table data.

Thanks!
