Database configuration problem

Hello!

I have problem whith installling drupal 6.2. I am allways stoped in 3. step - set up databaze. When I pushing save and continue I am again on the same page without any errors. what can be wrong?
I am sure that I am writing everyting right (passw, name...) because I wrote my own php srcipt and I connecnet to databaze without any problems.

what can I do with it?
