I cannot get multi-db to work and now my site is down

I was going through the install following the instructions and somewhere something went wrong. I get this message:
Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the wpglobal database.

Are you sure it exists?
Does the user meseek_wp1 have permission to use the wpglobal database?
On some systems the name of your database is prefixed with your username, so it would be like username_wpglobal. Could that be the problem?
I do not know what i did wrong help please.
