Mail Chimp oops issue

So I’ve read the older posts about connecting mail chimp form info. I’ve copied the link into the actions box under the Form settings and it is giving the Oops… message on the live site. I’ve checked and changed the things I’ve read to look at and no resolve.

I’ve read about zappier but I really don’t want to have to open yet another account just to get this to work.

If you can help I would greatly appreciate it.

I followed these steps.

I do not see any other steps for this process. Since it did not work I have changed it all back to normal but I would like to have the mail chimp set up soon without having to pay or sign up for another service outside of Webflow.

Any help you can give would be appreciated.
