Post your html/javascript so we can see what you have thus far.

This appears to be a 2-page exercise but you are trying to code everything on one page which is served twice. This can be done but is rather a complex approach.

It will be much easier to either:

  • Use one page and handle everything client-side with javascript (no PHP necessary)
  • Use two pages (the first page needs javascript and the second page needs PHP).

It's hard for me to advise as I don't know what constraints you are working under.
