Question

 $results = $mysqli->prepare("SELECT sound_link_droos.linkname, sound_link_droos.linknote, sound_link_droos.linkurl, sound_link_droos.date, sound_link_droos.rating, sund_cat_droos.catname, sound_cat_droos.catpic 
                              FROM sound_link_droos
                             INNER JOIN sound_cat_droos
                             ON sound_link_droos.catid=sound_cat_droos.catid
                             where sound_link_droos.accept='1'
                             ORDER BY linkid DESC
                             LIMIT ?, ?");

    $results->bind_param("dd", $position, $item_per_page); 
$results->execute(); //Execute prepared Query
$results->bind_result($linkname, $linknote, $linkurl, $date, $rating, $catname, $catpic); //bind variables to prepared statement

//output results from database
while($results->fetch()){ //fetch values
    echo '<li>'.$linkid.') <strong>'.$linkname.'  </strong> : '.$linknote.' : '.$catname.' </li>';
