  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

FileMaker custom function fnValidMBI(MBI) checks the supplied MBI identification and returns an empty value if valid. If not valid, the return value is an explanation of errors found. This format and rules for MBI are to be implemented after April 2018 and replace the old format for MC numbers which were based on the social security number, SSN.
