How do I use cookies to control which part of the timeline to play from?

Question

Hi there,
I have created an animation with Adobe Edge. My site uses Concrete5 and I am pulling in the Edge content into an IFRAME on my home page (there my be a better way to do this and I'm open to suggestions). I want the animation to play from the start when someone first visits the site, but if during their browser session they navigate back to the home page, I want the animation to only play a shorter segment of frames near the end.
My question is, how do I use cookies to acheive this? I'm new to javascript/jquery.
I've included the following code on compositionReady, (found in another post on this forum) but don't have a clue how to continue...
// insert code to be run when the composition is fully loaded here yepnope(   {     nope:[       '/js/jquery.cookie.js'     ],   complete: init   } ); function init() { //create your cookie's initial values here } 
My temp site is here - http://79.170.40.43/nutcrackerdesign.co.uk/
On revisting the homepage, I only want to play from when the green 'How can we help?' button drops in.
Many thanks!
Russ

Hi, Russ-
I found this article, which seemed really helpful in describing how cookies work in JavaScript:

Remember that JS works just fine within Animate, so on your compositionReady, you can read your cookie and then set the play based on that.  You should probably uncheck the autoplay for your Stage and control the play of your Stage from the compositionReady.
Good luck!
