This is the code i’ve got, basically checks finds the x,y position of number 2 in a multidimensional array. For some reason sprite.px = x and sprite.py = y give undefined messages when i trace them. What am i doing wrong?

[AS]  
for (var x = 0; x\<map[x].length; x++) {  
for (var y = 0; y\<map.length; y++) {  
if (map[y][x] == 2) {  
trace(x);  
trace(y);  
sprite.px = x;  
sprite.py = y;  
trace(sprite.px);  
trace(sprite.py);  
}  
}  
}
