gotoAndStop() does not work in AS 2

[clausrei]

Hi,

I have not much of a clue of Action Script. I try to build a Flash menu.
Every time someone presses a button he will redirect to another webpage - that works fine. But I also would like, that the banner above the menu changes every time you load a new page.

Now, on the loading webpage I pass a variable with flashVars like this:

<PARAM NAME=FlashVars VALUE="num=40">

And in frame 1 of my Flash-file I have:

gotoAndStop(num);

But this seems to work sometimes and sometimes it does not.
What did I forget ?
Any suggestions welcome, there must be something important.

Thank you for your help!
