Expression is the expression that evaluates and formats the label (text).  This can be a simple as a single field name enclosed in brackets or as complex as a script written in the language specified by the ExpressionParser.  If the expression is a script it must contain a function call FindLabel and the IsExpressionSimple property should be set to FALSE.

This can be based on either VBScript or JavaScript.
