Uncaught ReferenceError

I’m getting error:

$x(“.enhance_shortcode_menu_inline, .enhance_shortcode_menu_inline_list”).each(function() {
var id = this.id;
menu_superfish(id);
if($x(“#”+id).find(“.sub-menu”))
{

//$x($x(“#”+id+” li .sub-menu”)).each(function(index,element){
// var max = $x(this).parent().children(“a”).width();
$x(this).css(“left”,max+10);
Uncaught ReferenceError: max is not defined
//});

$x($x(“#”+id+” li .sub-menu .sub-menu”)).each(function(index,element){
$x(this).css(“left”,”100%”);
});
}
});
