Title: Fix PHP Warning for undefined index

I was receiving the following PHP warning when submitting the signup notice: `Notice: Undefined index: MMERGE4 in /root/wp-content/plugins/mailchimp/mailchimp.php on line 13791`. I'm not sure what the root cause was but this prevents the PHP warnings from happening.
