acess array from function

[tom_kristianm31618599]

i'm trying to make a 2d game, i'm still pretty new in flash, but here's my solution to the colision detection.

stage.addEventListener (KeyboardEvent.KEY_DOWN, keypress);
var zone11:Array = new Array(20);

zone11[0]  = [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1];
zone11[1]  = [1,0,1,1,1,1,1,0,0,0,0,0,0,1,2,1,1,1,1,1];
zone11[2]  = [1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,2,1,1,1,1];
zone11[3]  = [1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1];
zone11[4]  = [1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1];
zone11[5]  = [1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1];
zone11[6]  = [1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1];
zone11[7]  = [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[8]  = [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[9]  = [2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[10] = [2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[11] = [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[12] = [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1];
zone11[13] = [1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1];
zone11[14] = [1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1];
zone11[15] = [1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1];
zone11[16] = [1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1];
zone11[17] = [1,1,1,1,1,0,0,0,0,0,0,0,0,0,2,2,1,1,1,1];
zone11[18] = [1,1,1,1,1,1,1,0,0,0,0,0,0,1,1,1,1,1,1,1];
zone11[19] = [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1];

trace (zone11[1][1]);

function keypress(){
  trace (zone11[1][1]);
}

However i keep getting "Error #1063: Argument count mismatch on spilltest_fla::MainTimeline/keypress(). Expected 0, got 1." on the second trace, but the first trace is fine. why?

Set the function argument:

function keypress(e:KeyboardEvent):void {

trace (zone11[1][1]);

}
