I would like to use OptimizeParameters in conjunction with MetaCost.  I would like to iterate through Type II error costs between 1 and 10, and determine the best trade-off between Type I and II errors.  I saw another post that said you could define a Macro, which I did, and called it CostVal.  Then in the OptimizeParameters, I set the value of the macro CostVal.  Then in the MetaCost matrix, I tried to specify the cost using %{CostVal}.  However the tool would now allow that macro to be set.  It changed the cost back to a number.  It did the same thing when I tried to change the process XML file.  Is there a solution to this?
