Email address validation

[Guest]

Hello,

I'm currently using the following validation rule for emails in my form.

Like '*@*.*' And Not Like '* *'

This is just a simple way to check whether the correct format is being used
for e-mails.

However, I've run into a problem that if a user deletes an e-mail address
that is on the form and wants to leave it blank, it triggers this validation
check. Does anyone know what statement I can write to allow a deleted address
to go through? I can delete the email address from the back table but I don't
want to do that every time.

Thanks!

Try:
Is Null OR ((Like "*?@?*.?*") AND (Not Like "*[ ,;]*"))
