url parametes says "PageOK"

I have added the below code to functions.php in a hope to use http://www.mysite.com/out/?url=www.google.com but it does not work.

// use parameters to pass data
function add_query_vars( $qvars ) {
    $qvars[] = 'url';
    return $qvars;
}
// hook add_query_vars function into query_vars
add_filter( 'query_vars', 'add_query_vars' );

I have used in my page “out”

global $wp_query;
if (isset($wp_query->query_vars['url]))
{
echo $wp_query->query_vars['url'];
}

when I enter http://www.mysite.com/out/?url=www.google.com in my broweser it says “pageok”.. any help what am I doing wrong here.
