Add User using Listbox and then email

I have a form ([login to view URL]) that has two listbox. The users can select a name on the left listbox and move it to the right listbox. From there the users sends the right listbox information through email. About 95% of this works. Problem #1 --- All the information is sent over... except for the right listbox. (the left listbox we can ignore) Problem #2 --- The filter (javascript) doesn't work. I found this script here at: [login to view URL] . It's suppose to filter the left Listbox.
