having an issue with SmoothDiv Scroller

having an issue with SmoothDiv Scroller

I am trying to accomplish something similar to another post on here( hence why I put it in this area),

my issues seem to be similar with a twist, 
1st issue is the right side does not seem to trigger or do anything .
2nd issue is getting the scrolling to be smooth.

here is a link to what I have happening now. 


the one in question is the "my work" just below the fold.

thank you in advance
Jeff
