slideToggle function problem

Hi there,

I am in the process of designing my portfolio website and I am using jQuery for the first time so it’s taking me a lot longer to get results but everything seemed to be working fine before this problem…

I am using the slideToggle function with my navigation so that when a link is clicked, a sub list of links smoothly animates down.
This was all working perfectly until I began to style my page using image-replacement to replace the text with an image of the font I wanted to use.

As you can see here: http://www.ellekorhaliller.co.uk/jQuery/fannieaw.html#
The slideToggle function is working perfectly
but on this page, which I have just styled: http://ellekorhaliller.co.uk/jQuery/index.html#
it doesn’t work at all and when you click on “Commercial” you can’t even get the sub list to scroll back up.

Can anybody help at all??

Many many thanks in advance,

Elle.
