Help With Dashcode

Hi I'm making a widget on the dashcode application and I am having a hard time trying to figure it out...I am finding all the add ons really easily and am able to put them on the widget how I want them but am unable to figure out how to get them to do what I want.

I was wondering if there is a website that explains this a little better in detail or maybe a tutorial somewhere other than the apple website....if anyone could help that would be great....Thanks!
