Dobrý den, potřeboval bych poradít. chtěl bych rozdělit seznam aby se zobrazoval na více stránek.
ten seznam ne tvořenej ze zobrazení několika položek. tady je adresa .. http://www.srovnejokna.cz/poptavky 
const pzn=33;

$sql=new mysql();


$c_arr = array();

zkoušel jsem to vyřešit takto 
$pocet=10;



if ($_GET[stranka]) $stranka=$_GET[stranka];
else $stranka=1;

$page=($stranka-1)*$pocet;

$qp = new pager("SELECT * FROM poptavka WHERE zalozeno > DATE_SUB(NOW()),'stranka',$mysql->sql_connect);
$qp->PageSize = $pocet; 
$qp->PagerAlign = "center";

$qp->DataBind(); 

$firstLastMode = new FirstLastPagerMode(); 
$qp->AddPagerMode($firstLastMode); 
$prevNextMode = new PrevNextPagerMode(); 
$qp->AddPagerMode($prevNextMode); 
$neighbourMode = new NeighbourPagerMode(); 
$neighbourMode->NeighbourPagesCount = 1; 
$qp->AddPagerMode($neighbourMode); 

$q.=$qp->DrawPager();
ale nefunfovalo to.
chtěl bych aby se vzniklá tabulka rozdělila na více stránek třeba po 10 položek.

?>
jen nevim kam mam dát 
$qp = new pager("SELECT * FROM poptavky ORDER BY ID DESC",'stranka',$this->sql->sql_connect);
$qp->PageSize = $pocet; 
$qp->PagerAlign = "center";
$qp->DataBind();
echo $qp->DrawPager();
ale když to tam dám, tak se stránka pak ani nenačte, nevím kam to mam umístit
