Aza,
What kind of data are you using this tool on? Is this a feature class in a file geodatabase? Excel Table?
The results window shows "CCTVs\CCTV Phase 5C\CCTV Phase 5C".
I usually try to avoid spaces in the names when scripting or gp tools are involved. I don't think that would be the problem, but you might try creating a copy with a different name without spaces and give it a try.
