How to scroll a symbol with a separate button

Hi, first of all im sorry for my poor english, it isn't my native languaje.

Im creating a simple web site in Edge Animate and I'm need to create a separated button that scroll an especific element with an overflow:scroll in certain number of pixels.

Here is an simple example of what I need to do:

I need to make that the pink button scrolls the yellow box in to the 7th line of the text. In this case the yellow box is grouped in a symbol placed in the stage with the pink button.

I was trying with these codes:

      $("box").animate({scrollTop: element.offset().top}, "slow");

and

      $("box").animate({"scrollTop":"600px"}, 750)

But they aren't working at all.

I will appreciate any advice. Thanks in advance.
