Small rotating part within a bigger button

Hello - I’m having real trouble with something which I’m sure is simple Flash programming, but I just can’t see what I’m doing wrong.

I’ve got a big button (250 x 156 px). I would like the whole image to be the hotspot for the button. Within the button I have a smaller triangle (25 x 20 px), which I would like to rotate clockwise one point when the user rolls over the button then stop. I would like it to do this every time the button is rolled over. I’ve attached a simple image of this button to this post -

If that doesn’t work, it’s here: http://server5.pictiger.com/img/55213/other/dummy-button.php

I’ve tried following the tutorials here, but just can’t get it to do what I want. If any of you could help I would be most grateful! Thanks!
