Can't get pop-up windows to work on my site

[CSemerad]

This could be a script error or it could be something else, but the pop-up windows that were working are not now. They are product detail windows with an add to cart button. I have attached the script from the page if someone can look at it and see if there is an issue with the writing. I don't think I have ever changed anything on this page in order to not make it work, but I have been adding Java scripts to other pages on the site, if that makes a difference. Let me know if other page scripts are needed, or the website address. Thanks everyone! You all have been very helpful in the other forums!

What's all the stuff in curly brackets (braces: { }) about?  Are you using a templating system?  DTML?

This is not a complete page you have posted here.  Perhaps you could provide a link to the page - that would be easier.
