Group Field Names Can No Longer Begin with a Number
In the past, Group field names could begin with a number. For example, a Group could have a field named "1Address". This is no longer allowed, as a rule has been put in place forbidding field names from beginning with a number. This is so that field names can be compliant with VBScript variable names, for those customers wishing to use VBScript conditional logic statements within the body of their e-mails.
