Crikey, it looks terribly complicated for what looks like something to page through a set of results. Wouldn't it be easier to do away with the ereg_replace()? if($go=="next") { if($page < $nr_pages && $page >= 0) { $page++; $start = $page * 20; } } $qry = "SELECT L.Tunnus,N.Nimi,L.ISSN,L.Vuosi,L.Lisätietoja,L.Vuosikerta,L.Numerot,L.Huom autuksia FROM uusi_lehtitaulu L, nimet N WHERE (L.Nimi_id=N.id AND N.Nimi LIKE "asdf") LIMIT $start,20" Even it this doesn't work, at least it's easier to understand :) -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk /* The way to love anything is to realize that it might be lost. */
