error message

I have tried to manually install a new wordpress blog on a private host.

I get an error message:

Fatal error: Call to undefined function wp() in /home/vhosts/www.builders-of-jerusalem.com/wp-blog-header.php on line 14

Here is the file (with line 14 in bold):

if ( !isset($wp_did_header) ) {

	$wp_did_header = true;

	require_once( dirname(__FILE__) . '/wp-load.php' );

	<strong>wp();</strong>

	require_once( ABSPATH . WPINC . '/template-loader.php' );

}

What should I do?

Thank you!
