Having a little isssue with a if statement :(

programming flash
1 
clicked = 0;

if (clicked == 0) {
	trace(clicked)
	elements.cselection.onRollOver = over;
	elements.cselection.onRollOut = out;
} else if (clicked == 1) {
	elements.cselection.enabled = false;
}

elements.cselection.onMouseDown = function() {
	clicked = 1;
	trace(clicked)
	this.gotoAndPlay(17);
}

Basically if the button is clicked I set the variable to 1, so the hover and rollout should be disabled but for some reason it is not… any ideas?
