Where:
ConditionalExpr is an expression that evaluates to True or False.
ExprIfTrue is an expression to be executed if CondiionalExpr evaluates to True.
ExprIfFalse is an expression to be executed if CondiionalExpr evaluates to False.
Only one of the two expressions (ExprIfTrue or ExprIfFalse) will get executed each time the IIF function is executed. Either of these expressions can be any valid single line expression, including additional ("nested") IIF functions.
