JQuery Code Not Working (Positioning Nav at a fixed point)?

Question

Hello So lets just cut to the cace,
This code does work outside of Edge but doesn't work in edge. . . .
$(window).bind('scroll', function () {
        sym.$("arroworb").addClass('fixed');
The Object i want to keep in its place at all times even if the scroll bar is moved has the div ID of arroworb. . .
I have no Idea what i am doing wrong but yeah the code does work it just doesn't when put into Edge
My guess would be the window or blind has something to do with it not working but I have no idea how to fix this,
Any idea's?
Thanks In Advance!

Here is a small example, using animate, as Joe mentions.
In Stage > compostionReady
$(window).scroll(function(){
       var element = sym.$("arroworb");
       element.stop()
  .animate({"marginTop": ($(window).scrollTop() + 30) + "px"}, "slow" );
