using a macro in the metacost operator

Mori111

Hi. I set a macro named "churn-active" inside the cross-validation process and place %{churn-active} in the cost matrix to enable me to change the cost of churn-active in the Optimize Parameters operator. But the problem is the macro doesn't work and it backs to a number in the cost matrix. Did I miss something?

Hello @Mori111

Can you check if the macro is fetching the value you need ? You can got to View --> show panel --> macros. This will enable a window when you can see the fetched value by macro once its run. 

If you want us to check, please post your process .rmp file by exporting (File --> Export Process) and data set here or in private message.
