an unidentified error has occured? trying to connect with database for forms

I am new to website development and have been using dreamweaver for my website.

I am using WAMP server and have all my files on the host.

In dreamweaver when i add the database details:

connection name : connlogin

mySQLserver: localhost

username: root

password:

select database:

when i go to choose a database i get the error "an unidentified error has occurred"???

i try typing the database name and click test and still get the same error messages. all the tutorials i have been following say it should show the databases...

Just for clarity i have created my database and tables. I need to link my forms to the database.

I have searched online on various forums and cant seem to find a solution that works.

if anyone can help it will be much appreciated.

Thanks
