HELP with Input text to prefilled form in HTML

I have an input text box on my flash movie that will accept a zip code. And I need to have the zip code that is entered in the flash movie, prefilled on another form on an html page once it is submitted.

Order of events:

  1. User enters zip code into the (input text field) flash movie.
  2. User clicks submit
  3. User is taken to another page containing a form field with the zip code pre-filled with the entry from the flash movie.

Any help is greatly appreciated. And I do need to follow this sequence of the user confirming their zip code twice - so the page following the initial zipcode entry is definately needed.
