[Plugin: Joomla/Mambo To WordPress Migrator] [Plugin: Joomla/Mambo To WordPress Migrator] DB connect

As above describes: where in the Joomla and WP database paramers I must compile MySQL Server, Server user and paswd, do I must compile those fields with the server’s localhost parameters?
Because, altough I do like that, the error is:
Cant get MySQL Connection.0 –
If I compile it with different parameters, the error is the 1044.
If I don’t compile it:
MySQL Connection and Table Data not complete !!!.

Can you explain how to do it?
