Most methods of defining multiple script parameters require that the developer place the “sub-parameters” in a specific order and then call them by number. By using the Evaluate and Let functions, GetParameter( ) allows you to give each sub-parameter an intuitive name, then call it by name, regardless of where it falls in the full Script Parameter.

Not only is the order of the sub-parameters irrelevant, but so is the number of sub-parameters. If OrderID is the first of five subs in one Script Parameter and the eighth of fifteen in another, the function will work just as well.

Caveat: any sub-parameter that can conceivably be empty must be enclosed in a Quote( ) function. Otherwise, the Let( ) function within GetParameter( ) will fail.

Update: added error trapping for nonexistent subparameters.
