I’ve been stuck with such an error for 2 days now, and however I search on solving this from the number of previous questions asked about this error, I still can’t seem to get it to work, mainly because I don’t understand it at all.

Every time I enter the door with a hittest to the next scene, the error goes: 

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at gallerycopy_fla::MainTimeline/collision()

The code’s pretty long so I’m just gonna put the FLA (CS5) file here: http://www.mediafire.com/?129c41thb1u38c4

Thanks in advance.

    Simple…
    the function collision() is not accessible after frame 4 because of the blank frame, but the EnterFrame still calls it.
    One way to solve it is to extract the L1_actions layer to frame 10 (and delete the black keyframe)
    or rather cancel the enterframe event on frame 4:

    stage.removeEventListener(Event.ENTER_FRAME,collission)

    Do whatever is best for you project.

    And small advice, what you did shows great talent, I would suggest you to stop coding on the timeline and move to coding using some code editor (flash builder \ flashdevelop etc)

    Good luck
