Joe, Your code snippet does not make sense to me. If both NetProfitpc and RecFactor are negative, then ProfitMetric will never be positive (i.e. negative plus a negative equals a greater negative), and your condition will never be true.
Thus, your expression ProfitMetric = abs( ProfitMetric ); will never be evaluated and would have been redundant anyway, since you would only have executed it if you had found ProfitMetric to be positive in the first place and abs() just renders a negative number positive while having no affect on a positive number. Am I missing something?
