Adding navigation to parallax scrolling website?

Question

Hello!
I'm building a parallax scrolling website, with different sections.  The scrolling in question is quite long, so I have some navigation set up on the side to jump to the needed place on the timeline. 
How would I go about this?  I tried using the stop at, but it acts wonky with the scrolling...it jumps to the label, but it doesn't seem to take the scroll navigation control into account.  I also tried using the following code:
sym.$("stage").scrollTop(0,2157);
...but it jumps to the top of the site, every time, no matter what x/y coordinates I input.  I am using the following code to control the parallax scrolling on the stage: 
// scrolling controls animation
var animationHeight = 24000
var stageHeight = sym.$("Stage").height()
var scrollPos = sym.$("Stage").scrollTop();
var duration = sym.getDuration();
var percent = scrollPos / (animationHeight - stageHeight);
var time = duration * percent;
// Update timeline
sym.stop(time);
Help? 
Thanks,
Chad

So, I figured this one out. 
If you want to add navigation that jumps to a particular point in the scroll, the above code is correct, however, my number was switched. 
I have a hidden object named "floating stage" that I use to tell me where the browser window is at any given time.  I mark the Global X/Y position for the point I want to jump to.  My marker's global position was X: 0, Y: 2157.  I was putting in the correct numbers, but they need to be switched for the code.  Not sure why, someone smarter than me who has a better grasp on coding could probably give us all an answer. 
SO.  Select your text/navigation button/whatever, click on the add action button to the left of it, and add a click action. 
Then, type this in:
sym.$("stage").scrollTop(2157,0);
When you click on that particular link, it will jump/scroll to the point indicated in the action. 
Thanks!
