Not enough to go on for the DevRef without the rest of the project.
However, what you posted does have a bunch of errors highlighted by all the red dots.
All the enumerated types used aren't the right ones for Relay.
Get one correct Relay Enum by
- Deleting the wire into Relay (the one with the red dot)
- Right-click on the now vacant Relay input node and choose Create->Constant
That's the correct Relay enum type.
- Now make copies of the correct one and replace all the others
- Finally, remove the Enum you created into Relay and wire Relay into the Select as it was before.
- If done correctly all the red dots should be gone.
P.S.
What are you using this Relay for?
Forward, Reverse, Off are an unusual combination unless they're LEDs or something like that.
