First of all we don't know where the posted code goes. Could you set it up so that we know what code is on the keyframe, what code is on the player, etc. But if the platform is just a simple movieClip then you could run a check through your platforms to figure out which platform he's hitting and then set the guy._rotation to the platforms._rotation ( _root.guy._rotation = platform._rotation ) I'm not sure if you could do it with your current set up however, you need a way to find out which specific platform the guy is touching.
Lol, with a name like that you might want to try and 'h4xx' yourself there, since A) a respected community member takes the time and effort to reply to your post and B) he has a valid point. You supply us with a block of code yet - like he already said - you don't say if it's placed on a keyframe or the movieclip, since it's obviously AS2.
And, C) the post Zrb made is - though a bit short - everything you probably need. I haven't scanned it thoroughly, but from a quick glance it gives out exactly the code you need...
