//  Name  : ft_formValidate
//  Version 1.2 Original Author: Marion Dorsett - http://www.FigmentThinking.com
//  Modified: Mike Sharp - rdcpro@hotmail.com
//  Version: 1.2-modified
//  Changes to allow error message to show friendly field name, which is passed in the second argument.
//  A result of this change is the IsMatch doesn't work (which is ok for this particular instance).
//  IsMatch needs to be modified so the match field name is part of the IsMatch parameter, like the InRange.
