Hi,
Coule you suggest me how to validate multiple email address separated by a semicoln ";" in a textbox in infopath.
Right now i am able to validate a single email address by using ([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)
in the custom pattern ...
