Hi

I'm a noob just trying to get my feet wet in the world of APEX and triggers. Help or direction here would be greatly appreciated.

I've got a custom object that tracks CSAT results for Cases. When the CSAT record is created, I want to populate 2 user lookup fields on the CSAT custom object: one with the last modified user on the related case; the other with the manager of the last modified user on the related case. 

I've had a few starts at doing this. But I'm getting stuck on where to start. All the examples I've found seem to take me in circles. 

Thanks!
W
