[Plugin: Pinoy Pop Up on Exit] How would I make this work with Romancart?

I know very little about code and would really appreciate a little help if possible. I have built a site and use romancart for my shopping basket. The button code is below. How would I add the extra code to this so that the pop up stops?
<form action=”http://www.romancart.com/cart.asp&#8221; method=”post”><input type=”hidden” name=”storeid” value=”11111″ />
<input type=”hidden” name=”itemcode” value=”JSG” />
<input type=”submit” value=”Download now” /></form>

Thanks
