Ok..if currency aint your thing how about EMail Validation? :) On the register.asp page (code below), how do we make sure that only an email address is entered. we only need a very basic one - one that makes sure there is some text followed by '@' followed by some more text and a '.' ending with text eg 'com'. If for example
[email protected] is entered we want the system to run as normal, but if Test is entered, we want a message to read please enter a valid email address. Much ike the message is shown for the password validation.
Thank you for any help you can offer:)

}
