There are potentially a few problems using javascript to control the number
of submits:
#1 non-javascript compliant browser (there are still a few out there... ie
some (all?) WAP browsers/handhelds
#2 What happens if the submit failed? Then you just made the user restart
the whole entry sequence over?
I think the session variable idea Daniel posted might be better since,
since if the submit failed, the sesion variable will not be set.
