Can someone help me with Scrollto and Prettyphoto plugins.

Hi there.
I'm building my website based on Scrollto plugin. I added Pretty photo plugin for the portfolio page.
As I'm new in Jquery, I can't make them work well together.
I'd appreciate if someone can give me a quick help.
Here is the link of my website.

Thank you,
