I am trying to create a thin line under a nav bar to follow the mouse but am having trouble getting e.page:X to set the width of the element.

Here is what I have:

$('#test').mousemove(function(){
var linewidth = e.pageX;
$("#line").width($linewidth);
                              })
})

Can anyone tell me why this is not setting the width of #line
