See? That's what I mean when inexperienced site owners use "pre-made" templates, such as SiteBuilder and many others -- you don't even know if your site has code errors/warnings; nor do you know if your site displays properly in all browsers ... that alone can hurt you.
First thing you need to do is, place the correct mandatory <!DOCTYPE Declaration>
at the top of your site -- how do you do that? Simple -- go to the W3C schools website shown here
and read up on which one is correct for your site.
Then, you have one major code warning that appears numerous times -- <script> isn't allowed in <tr> elements
... we'll cover this after you've found, and placed the correct Doctype Declaration in your HTML syntax.
