Detailed Description
The label Simple expression expects to hold a legal, Simple script and to be read and evaluated by a Simple expression interpreter. An example expression that combines text with a field value is
"State: " CONCAT [State_Name]
Note that quotes are needed around the literal text. See https://developers.arcgis.com/documentation/common-data-types/labeling-objects.htm for full documentation on the <b>labelExpression</b> syntax and functions.
