phew it gives a lot !

But I discovered one thing:
When you enter the site, there is no variable named ActionList, but when
you hit the submit button there is a ActionList with value=1

hmm .. what now?
I need to test for that variable but it has to be declared before
running the script.
Has anyone had these kinds of problems ?
