Attempting to create a mod, stuck with an "Invalid neural Function" error

So I’ve been working on my own mod for personal use and, after finishing the Situations and Simulation csv’s I decided to test them. After troubleshooting some mis-named inputs and outputs, I’m now stuck with an “Invalid neural Function” error (specifically "Invalid neural Function:…\src\SIM_NeuralEffect.cpp 128) and have been unable to fix it as of yet.

I’ve gone through all of the error and debug logs, but aside from a line listing the above error, I have no other information to go off of. If someone could help me out with this, it would be very much appreciated. I can also post the csv files if need be.
