Try fixing your html first.
Code:

There's only one </li> in there.
The anchor title makes no sense.
It looks like your trying to show text in an img src tag
You have an image border as well with the same image?

There. Fix the html errors shown there and then we can go from there. Your main issues will start with the "
Line 68, Column 122" error. You should fix it so its declared as xhtml though.
