Hi there,

I am designing a front end interface for a website. All is well but i'm facing a problem of navigational system is not working in IE7, its working fine for other browsers.
Please check this link:

when page will be loaded then you can see a big picture of LCD & camera in center of the page, move the mouse on the navigational links at right side of this picture, this is navigation system, its working fine in ie8, firefox, safari but its not working in ie7.

I am trying to fix this bug, can anyone give me a suggestion or solution to fix this bug?

Regards

There are a few validation errors with your css. Try fixing those first.

Thank you JKing for your time but that was not a solution. I have resolved the issue on my own.
