Updated: 2019-03-18 - This version includes new brands and updated card number ranges for Mastercard, UnionPay and others. It also handles new 17-19 numbers as well as older 13-14 digit numbers. For current card number ranges and brands, see http://en.wikipedia.org/wiki/Payment_card_number for current ranges.

This is a revison of Geoff Well's implementation of Brian Dunning's Card Validator.
It requires that the 3 Luhn custom functions - Luhn, LuhnDoubleEven, LuhnProduct - available at

The following discontinued brands have been removed: Bankcard, Diners Club enRoute, Laser, Solo, Switch. I have also removed the detailed breakdown of various Visa cobrands such as Electron, Visa Purchasing, etc. Please reports any errors or suggested improvements in the comments at briandunning.com.

I think you need to add your Parameter to the name. i.e. CreditCardType (CreditCardNumber).

Because FileMaker is looking for CreditCardNumber as a parameter.

When I use the Clip Manager link, Clip Manager, provides reditCardTyp as the Parameter, which then has top be changed to CredCardNumber.
