>Hi,

>I have the following validation expression for an email text box. I need to allow an apostrophe to be in the email address. My understanding is that I need to add the apostrophe to the ValidationExpression ('). But I am not sure where in the following expression the apostrophe should be? Should it be in the first bracket, e.g. [-+.'] or some other place?
