Hi Travis, thanks for trying out ScriptAnalyzer. It seems like the variable $values was misspelled in the for loop though (as vaules). Once this is fixed, ScriptAnalyzer will not give out any warnings. Thanks!

sorry for the typo, I have several examples of this, but coming up with a simplified repro seems difficult. Please stop by my office and we can discuss the issues.
