Here is how to find the problem because no one can use your code to reproduce the problem without having all of the dependencies.
Get Firefox with the Firebug
You can select elements within the browser and get all of the CSS and HTML for that element then change these values so that you can find what the problem is. This is a must for UI development.
In addition you can debug JavaScript by setting breaks in the code live.
