Can anyone check my drop-down menu pleeaaasse?

Can anyone help me please?
I have a javascript drop-down menu in an HTML file, and the links on the
menu items seem to be a bit temperamental. I'd really appreciate it if
someone could take a look at the source of the attached URL and give me any ideas. The drop-down menu is on the "Our products" button.
Thanks.
