Good Afternoon from truly tropical 20 degrees C wetherby UK :-)

On this page and illustrated here: I followed this tutorial:

But the drop down effect I expected to see trigger under the home tab just doesnt fire, i did the following before posting this:

1. Checked selectors were selecting
2. Made sure the Javascript snippet was in the correct locatiion and tweaked to select #menu
3. Played around in Firefox varius tools to se if any tweaks would make a difference

But nothing works :-( Maybe I have a Jquery script conflict, I'm lost for a fix.

Any insights welcome :-)
