Javascript/PHP Help

I'm trying to parse a variable when clicking a checkbox on a page, I'm trying to do it using this code but it isn't working.

function returns(filename) {
	var x = new Image(1,1);
	x.src='http://database/othering/returns.php?filename='+filename+'&x='+new Date().valueOf();
	return false;
}

Can anyone advise?

I found the problem, my onclick didnt have ' ' inside the brackets.
