Enum and Ring Data Types - Discussion

[SercoSteveB]

I like this question but can't settle on a good set of multiple chioce answers, so thought we would have the first Discussion question.

Consider the following VI.  We have wired Enum and Ring data types to two Case Structures.  The Case Structure receiving enumerated data accepts "Likes LabVIEW" as a Case Selector Label but the Case Structure receiving ring data does not (as shown by the red text).  Why?
