I want the variable "score" to increase by one when the condition is true.
However "score" doesn't alway update and sometimes adds more than "1". "this.removeMovieClip();" only works randomly.
The mc flip1 is triggered by keypress(left).

if (_root.flip1._currentframe=2 and this._y<450)
_root.score = _root.score+1;
this.removeMovieClip();
}

How can it be?
