Macro sometimes works. Sometimes does not work

[fierceanalytics]

Update: 

With the code corrected, therefore controlled, managed to isolate why that bad code lasted for 2 days. Turned out the installation had some "flu-like symptoms. It was actually randomly "doing /not resolving" macros. We applied a patch Saturday. Now the bad code never took off without error me out. Without the code being correct, hard to realize the system side. So thank you all.
