How do I gotoAndPlay(frame); depending on a variable from php?

Ok, I have set the variable in my page using <param name=“flashvars” value=“menustate=<?php $pagename; ?>”> which works perfectly fine when I use a dynamic textbox in flash with the var name menustate.

But I need to send a MC to frame 2 if ‘menustate = 2’. Anyhow, I just want to know how to control a MC with an external var. I can’t use loadVars () because this var is coming from any page, not just one.

Thanks,
