need help inserting php script

i installed this script http://www.tutorialms.com/downloads.php on my site (http://thesitepro.info/) but i get an error i dont think i have installed it right iam hosting on http://www.000webhost.com/ can anyone help or do it for me.

 

it would help a lot if you can describe what the error is, users are quite weary at clicking links

 

you can see the errors by clicking on the site http://thesitepro.info/

 

That error is pretty simple to fix.

Just go look in the config.php file and make sure the SQL database you created has the same user and password information in it.

 

that the part i get confused in is there anyone that can do it for me .
