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?

Have you right-clicked the node, and clicked Refresh Node?

That worked, thanks!
