That's your first mistake. Never do validation in an onblur event.
Validate when the form is submitted (onsubmit.)

Use syntax like document.forms['form1'].elements['email2'] to
reference the elements.

See above. Also, this illustrates the problem of validating in the
onblur event. What if a user first focuses the email2 element, enters
an address and then attempts to focus the email element? At best they
will get a useless alert.

you focused the email element.
