Hello @BarbS8227 ,
You'll need to make sure the personal account you're logging into is an admin on the Facebook business page you're trying to connect. If you're not setup as an admin, and it's not a true business page, it won't be available to select when you login. It may also be worth checking that page's settings to make sure there's nothing that would be preventing 3rd party integrations or connections.
