Square zoom on mouse over

[Rajesh_Kunnath]

how can i make a square zooming continuesly on mouse over

the script i’ve written is not working . it is working once on rollover.

square.onRollOver = function() {
i=2;
square._width = square._width+i;
square._height = square._height+i;
for(i=0;i<=400;i++);
};
