Rollover menu - click through problems

Hi there. Firstly I am very grateful to anyone who may be able to assist me. I am fairly new to Flash and have I think a simple question.

I have a sample flash file, when you pass your mouse over one menu item - two other menu items appear and you can then pass your mouse over either of them and click.

My problem is nothing happens when you click - I would like to jump to a new frame later on in the movie to start another animation? Depending on what you click on.

I have attached the sample file - what do I do write and where for the action script to goto and play. Nothing seems to be working for me. Attached is the file.

I am using FLASH 8.
Thankyou!! :hugegrin:
