Issue with Override file

Hi,
I've changed the hover colours for the menu and it all works fine except for one tab. There doesnt seem to be any issue and I just cant figure out how to force it to work like the other files.
Thanks

Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
