Non-object error, how do I fix it?

I don’t know much php but a little, it was more this bit I meant:
usedb( “blog”,“dbLinkInt” );

In the header file I’ve put it exactly as that but didn’t know if that was right?

Did you try it and see if it works?

Yep and I got the same error. I’m trying to get it to work with WordPress but I don’t know which table in the database it’s trying to use. I’ve added this to the header.php file:

# blog usedb( "blog","dbLinkInt" ); $query="select * from wp_options"; $result=dbselect( $query,"dbLinkInt" );

I know that that database and table exist but I still get the same error

So this line tells me one of two things:
1: Your code seems to expect a MaxDB object.
2: Your code expects a customized database class. [PDO does not abstract a connect_errno property; neither does any class i can find in the PHP reference].

Is it possible to fix it?
