I tried to install Multi-DB, but first step is the first

Hi,

I tried to install Multi-DB, but first step is the first problem.
As I open the url with the move-blogs.php I got following Error:

DB Error, could not list tables
Make sure you configure your original table in the dbname variable at the top of the script!
MySQL Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-schnaepp20143' at line 1

In this line I inserted just the database name.

What can be the problem?

Thanks for help
