Hello @KarlaN57,
Thank you for reaching out to us on the Community!
I apologize that there is an issue with setting up a list, please click here for an article on adding contacts.
Have you tried opening Constant Contact on another browser to see if that fixes the issue? Also, sometimes using Incognito/Safe Mode will reveal that it might be a plugin/extension that is interfering with the site. If that does not work please email us at social_support(at)constantcontact(dot)com with your username, the troubleshooting steps you have tried, and a reference to this post so that we can investigate it further.
Thank you!
