That's OK. I can muddle on by in German.

Here is the real reason, I think...

http://dev.mysql.com/doc/refman/5.0/en/join.html :

I conclude that the error could be eliminated by putting parentheses ()  
around the comma-separated list of tables.

I'd be grateful. I can't test everything on everything!
