The Finish VI is where you can close and destroy any I/O resources your program has opened. It looks like the solenoid and DIO are actually Open VIs rather than the Refnum Registry Get VI that the other I/O uses.

So you can delete the Opens outside the sequence and drop the Solenoid and DIO Refnum Registry Get nodes, wire in the name of the I/O, and wire the refnums into close.

More to your initial question, the error code is saying pretty much the same thing I'll say. Your enumerated data types do not have the same values in the same order. If you show the help window and hover, you will probably see the description of them and be able to figure out which ones you want.
