Return node pin for function not working

Error on compiling: Could not find a pin for the parameter…

No output pin (Nval) will show up for my function.

Everything is connected, no orphans or broken links. Tried rewiring, rebuilding, manual values…

Out of ideas, any suggestions?



Clicked a node, and selected Refresh Nodes. Works.

Came here with the same issue. You saved me so much time!
