I have a site where users will log into a members area showing listings of titles,
they click on a title, it opens a pop-up window to display content,
then system sends email notification of that action and any requests made.
Its not working, so most likely scripting error.
Here's what will make your fix easy. I have another site that has the exact same programming,
so you can reference that to see how it operates and make the fix without much work.
