Refnum Defining

[Doug Norman]

Because the RefNum Get is outside the case structure, it seems it should be getting called - and the error makes me think it is. One thing to try might be to actually make a copy of the "Sensor" text constant wired to the RefNum Set, and wire that into the RefNum Get. This would be just to make sure the names are identical and there isn't some hidden or nonprintable text.

It would be really helpful if the error message included the name of the refnum it couldn't get. I can imagine helping a team at a regional having this problem where the main indication is an error on the diagnostics tab, and not really knowing where to start looking, especially if there are a lot of refnums.

This is good advice, but I've tried this too! It didn't seem to fix the problem.

Attached is my code and a picture of the error message.

UPDATE: I have reinstalled LabVIEW with the update and it has not solved the issue. Additionally, I tried another laptop and that gave me the same error.

How are you running the code? I don't see a Robot Main vi window open anywhere.

[Pausert]

From the teleop loop. Should I be running it from main? i thought that running it from teleop wouldn't be a problem as the other refnums didn't return errors...

[Alan Anderson]

If you don't run the Robot Main vi, the Begin vi doesn't get called. I think that should adequately explain the problem you've been having.

This is your problem. The program you run is Robot Main and it calls all the other sub VI's as they are needed or to run them.

Also your indicator is going to appear in the teleop front pannel not the driver station or robot main front pannels. You can have these front pannels open when the program is running though without any problems

Thanks for all the help. That seems to have fixed it.
