Beginner question

I am just starting out with Pipeline Pilot and am learning the ropes little by little. I have started by exploring some of the examples that come with the Pipeline Pilot Client. I note that when I drill down in a given icon, I sometimes reach a point where there is a reference to a server side script. How can I see the referenced script. This is an especially relevant question when errors reference a line number in the script. Thanks for the help.
