Integrating Mailchimp with Membership PRO

I hope all is well.
I tried to follow tutorial video instruction to connect Membership PRO to Mailchimp without any success.

I included 3 attachment to show that I have done already.
Please take a look and give me some direction.

I also have different Membership subscriptions. I would like to connect each subscription type to a different Mailchimp list.

Please HELP.
THANK you for your time.
