Menu Not Working In IE

[SalientAnimal]

Hi All,

I have a bit of a problem with the site I have been working on. Originally I built it on my laptop, to later transfer over onto the "Intranet" server.

On my laptop, everything was working perfectly and as intended. I then transferred it onto the server and when testing on the server it works perfectly as well.

I then access the server using the web address and on Firefox it works perfectly, however on IE my slide down panel does not work. The slide down panel is where a user would login / register, so with that not working they aren't even able to register / login

Here is the code of my index page, as I am not sure what other code to provide you with, maybe you can request any other info you would like to see?
