undefined symbol?

[Kohala2460]

When we run the code it runs a error code: "holds reference to undefined symbol" then displays a crazy symbol. What is it?

Is this LabVIEW? If it is, figure out what vi the error is coming from. I'm pretty sure there's a "show error" button on there somewhere.

Nobody can really help with just the information that the code doesn't work :p
