I am trying to write a code that will iterate through a table, and export each row in the table as a separate PDF. The first time through the loop works. The second time around it gives me the following error message:
Runtime error Traceback (most recent call last): File "<string>", line 21, in <module> File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\analysis.py", line 98, in Select raise e ExecuteError: ERROR 000732: Input Features: Dataset Congressional_District_7 does not exist or is not supported
I am using ArcGIS desktop 10.1
This is the python code, I have also attached a copy:

#Try an update cursor to resolve looping problem?
