3) Describe problem:



Hi, im pretty new to this stuff. I am from Northern Ireland, and im doing my Alevel website project on Microsoft Frontpage.

I decided i'd get ahead a little and have a sort of drop down menu.
Anyway i got it all sorted and it was all working smoothly, until it suddenly just stopped working....

Anyway here's where i got the code from...

However, now when i go to preview it, it comes up with these two errors..

......

This is what they look like atm on my navigation page with edited links...



..However, when i click on the bars, they do not collapse or expand, this is what i need to resolve.

The following snippet is from the code for my navigation page..

Also...below is what is within sdmenu.js

Code:

	}
};

	}
};

If someone can please tell me why they are no longer expanding or collapsing id be hugely grateful...also when it refers to the errors about SDmenu etc, it cannot because i have edited with a bad syntax, as i have pasted the default extracted original copy.
