hittest for scrolling map help please

[neomaximus2k]

Well I have been racking my brains off on this for what has been 2 days now and I still have not got anywhere.

Basicly what i want to happen is this.
the player presses a direction key, and the map moves in that direction (thus simulating a scrolling map) now when the character (that is constantly staying still) gets to the end of the map or hits a tree area then the map should stop scrolling but no matter what I do it just does not work.

I'll attach the FLA file but please do not steal the map. Took me ages to CG it into photoshop

Any help given will be shown on the credits once the game has been developed.

Please Help :'(
