Aspen Custom Modeler, Aspen Reaction toolkit

[pepsferr]

Hello,

I'm a beginner in the AspenTech's world. I'm tryng to build a custom kinetic (Monod) with Reaction Toolkit in Aspen Custom Modeler. I followed the Help of ACM to write and connect correctly custom model to Aspen Plus.
Now, in the Reaction's Setup sheet (see the pic below), I can see and the custom model ("Bio") in Aspen Plus but I can't use it for some reason or I don't know how to use it. Does anyone have a guide or tutorial?

Thanks for your time,
