Thank you very much for your comment!
Unfortunately, as I mentioned previously, the expression cannot be evaluated if it is placed in a module. The Evaluation function also gives you this notice, if you look at the screenshot in my previous answer. I believe this is a limitation with the Evaluation function, as it works more like a preview to test the function.
I am very sorry for the inconvenience! I highly suggest reporting this through your local reseller in order to ask for higher priority.
