ASP Link no refresh

I need this page to function as such Phase 1 1) When you click on Link 1 or Link 2 of section 2, it will affect section 1 with no refresh. right now the page refreshes 2) do not use iframes 3) maybe you can use java onclick to store sessions 4) the request parameters need to change on section 1 when you click anything on section 2 5) i dont think you need to do anything on [login to view URL] if the sessions and query strings are working. 6) make as stable as possible. i will incorporate this with a page that has a lot of css and java scripts 7) I need this done within 2 hours today since its not heavy coding. 8) It needs to be in ASP Phase 2 If you do it right, I will need your help setting this up on another page. That will be a new project separate from this. Here is the working link <[login to view URL]> I also attached the source code. My yahoo ID is mosfet93 if you have questions
