It hurts my eyes! I'm not saying this will solve your problems but if you validate the page and then correct all the errors you find, that will be a good start.
As Hooperman informs, try a validation (I've done it for you). http://validator.w3.org/check?uri=http://the-rich-jerk-review.info/ You have 48 errors, you might get rid of some if you give your page a doc type. You have more than one <body> tag. I've never built a site using Yahoo site builder so I can't say what special code they use for pages. In some cases some of the errors cuased my be just down to the code they use for building the site and no matter what you do you will still get errors. Try building the site (a page) off line to the way you want it, get it to validate and then transfer it to the Yahoo Site Builder. If it still looks odd after that you can assume its the Yahoo code that's messed up.
