Log summary issue

[Niugg2010]

I am learning to use SAS EG. In Log Summary window I right-clicked ERROR  and found "Go To Program Source" is inactive (please see below snapshot).

Is there someone help me to figure out the reason? Thanks

My SAS EG version is 7.15.

It says that's in the log line 52. Go to that line in the log and paste some of the lines before and after here.
