Mailchimp

I have tried everything listed under the mailchimp thread and that hasn’t helped me. I have this code in my [mc4wp_form id=”59″] form action field for the genesis e-news extender. I have changed the fields to only require email and first name. I changed the merge tags to match and I’m getting a 404 error. What am I doing wrong? 
 
Also, most of the wordpress videos are down and haven’t worked for about a week.
