Choose Function

Returns a selected value from a list of arguments.

Syntax:


Choose (Index, Selection1[, Selection2, ... [,Selection_n]])

Parameters:

Index: A numeric expression that specifies the value to return.

Selection1: Any expression that contains one of the possible choices.

The Choose function returns a value from the list of expressions based on the index value. If Index = 1, the function returns the first expression in the list, if index i= 2, it returns the second expression, and so on.

If the index value is less than 1 or greater than the number of expressions listed, the function returns a Null value.
