AS on different frame error

programming flash
1

Hey all.
I had this code on frame 1 initally and it worked fine, however i’ve moved it along some frame so I could put an intro to my game and now I’m getting an error.

The code is:

char_mc.[COLOR=#000000]addEventListener[/COLOR][COLOR=#000000]([/COLOR]Event.[COLOR=#000000]ENTER_FRAME[/COLOR], moveChar[COLOR=#000000])[/COLOR];

and the error I’m getting is:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Any help would be fantastic.
Cheers.
