Hi Jaysun,
I tried to use your code to work out your problem but there were many issues that made it too difficult to help you. Please could you create a test page and provide us with a url to look at? Also, try and rip out all of the Dreamweaver javascript as rolfsf said and use CSS for rollover effects, plus, put alt text in the images within the Superfish links. Without the alt text, when images are disabled or unavailable (as they were when I used your code) the menu completely disappears as there is nothing in the links to show.
Another thing to consider is that the HTML is not valid XHTML Transitional as the doctype claims. This could make cross-browser consistency tricky and could also affect how scripts run in the document. If you can, run the page through the w3c validator and fix the errors.
Once I deleted all the inline scripts and inserted text into the empty menu links, the menu did work, but due to the layout's reliance on images, we will need you to create a working url for us to look at so we can give you useful advice.
Joel Birch.
