Javascript Popup, weird behavior
 

What I have are some little calculators that popup when clicked. I can get them to work fine using them in either the detailed description or by putting them in the customer/home.tpl file. But when I do that the tabbed interface for Send to a Friend, Customer Feedback section goes wonky. What am I doing wrong? Pictures of before and after below.
