Selector values have wrong type

LabVIEW could not convert some of the selector values specified for cases in the Case structure to the same type as the selector. LabVIEW indicates this by displaying incompatible selector values in red. When you have a Case structure, the values at the top of each case must be compatible with the data type of the selector terminal.

The selector in the following illustration is an integer type. The selector value for the visible case is Z. This value is a string and not appropriate to the selector type of integer.

To correct this error, use the Labeling tool to highlight the selector value and enter an appropriate value. Enter quotation marks around a value to indicate that the value is a string.
