I can not proceed witht he poll instalation

Hi!
I made the changes to the db folder:
host: localhost
Db: database name which is a db that it is already exists
user: my user name
Pass: my password

When I upload the files and run the installer I could not go beyond the first screen where it says make the chagnes to config.php ...
please help me out

just create a database called poll... this will work ... (or you can change the hole code acording to your database name....
