Using Flashvars in Firefox

I’ve created a quiz that passes a final score over to an ASP page using “POST”. This works fine in IE but Firefox is another story. Can anyone help?

The value of the final score =score
The flash quiz is on a page called “game.asp”
The game is passing it’s value to a page named “entryform.asp”

Does anyone know how to solve this or know of a good article online about this - I can’t find one?

Much appreciated.
