PHP mySQL_num_rows HELL
===

    $i_id = $_GET['iiSL'];   
    
    require_once('../include/dbc.php');    

    $sql = "SELECT invite_id FROM invite_requests WHERE invite_id = '$i_id'";
    $result = mysql_query($sql);
    if(mysql_num_rows($result == 1))
    {
    echo 'GOOD ID EXISTS';
    //ECHO IS JUST TO TEST	
    } 
    else
    {
    echo 'BAD ID IS NOT IN DB';
    //ECHO IS JUST TO TEST
    }


Why is this not working? It's driving me insane. 

ERROR `
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource`

All spelling, grammar, syntax, and case is correct. URL is passing the `$i_id` variable. It echo's out correctly.

What am i doing wrong?
