clear_on_hide is there a workaround?

I’m in a bit of a bind, I’m working on a tight deadline on a site where someone can register and sign up at one of several soccer camps. The site owner also wants to be able to sign up more than one player at a time, and they can add up to 4 players in total and choose different camps for each player.

I’ve got it all set up to work correctly but unfortunately clear_on_hide doesn’t seem to be working at all, so if someone goes to add extra players and accidentally clicks on one of the programs before closing it, the price gets added to their total even after hiding.

It doesn’t matter if nothing else gets cleared, but I really need to be able to at least clear any of the checkboxes in some specific divs. I’ve tried several workarounds but nothing seems to be doing the trick, it’s sending emails correctly, but I have a hidden paypal button that is triggered on submit and it’s picking up the wrong totals.

Help!
