index	The index number (Integer).
choice1	The expression containing the first possible choice (Variant).
choice2	(Optional) The expression containing the second possible choice (Variant).

REMARKS

* The "index" can be any numeric expression.
* If "index" = 1 then "choice1" is returned.
* If "index" = 2 then "choice2" is returned.
* If "index" < 1, then Null is returned.
* If "index" > the number of choices, then Null is returned.
* If "index" is not a whole number, then it is rounded to the nearest whole number.
* All the choices have to be submitted as individual items, you cannot pass in an array.
* Every choice is evaluated in the list, even though only one is returned.
* This can be quickly used to return a selection without having to create an array.
* You can use the IIF function to returns one of two parts, depending on the evaluation of an expression.
* You can use the SWITCH function to return a value based on expressions.
* The equivalent Excel function is Application.WorksheetFunction.Choose
* The equivalent .NET function is Microsoft.VisualBasic.Interaction.Choose
