NameError: name 'target_id' is not defined

Output would be nice. I see a lot of print statements. And wrap you code in python tags please. The error message indicates target_id is not defined. I see where target_id is defined, but something must be preventing that code from being reached. Is it an indentation error? I can't tell because without python tags the indentation is lost.

What should i make change in code so that it works
