Help with basic code

Hi

I am trying to learn some rollover techniques (mainly so I can create a rollout effect). I found this site last eek and it’s extreamly helpfukl.

I followed the instructions from the Flash 5 advanced rollovers, but it seems not to want to work ;(

My .fla and .swf are here if anyone can help. http://www.fuci.co.uk/clientarea/testarea/

Applogioes for what must be a very simple noob question!

The button in question is the portfolio one at the bottom - the rest is just a guide I am using so ignoire that. It shuld load the movieclip and bring the other buttons out so the user can then roll over those (they are buttons too)

Thanks
