Can’t select database

I get this error when trying to set up the config. I am entering the database name correctly so I think it might be this part that is giving me trouble.

Does the user [username] have permission to use the [DB Name] database?

I may not have the permission set up correctly for the user, but I don’t see an option for changing using cPanel accelerated 2 interface. Would there be a SQL statement to use to change permissions?

Thanks for any assistance.
