Change button URL to Email

I’m trying to change the function of the button from a destination URL to a mailto: function temporary. I’ve even tried to remove the button entirely (as this is already behind an opt-in form), but can’t seem to do that either.

The form is on:
http://www.paperlesspcs.com/1435-2

and if you know how to get rid of the scroll bar also, I’d be indebted to you for ever.
