    $ret .= "<td background='img/gifs/box_topleft.gif' width='10'></td>"; 
    $ret .= "<td background='img/gifs/box_topmiddle.gif'><span class='headerOrder'>&nbsp; ".$itemCatName."  &nbsp; </span></td>"; 
    $ret .= "<td background='img/gifs/box_topright.gif' width='10'></td>";

inte vill visa sig vad kan detta vara?Beror det på return tro och vad skriver man istället.
Jag kan inte skriva echo för då blir det ju fel.

//Show products mainPage 3 in row.
