[edit reason] removed css/html [/edit]
The problem lies within here:
if ($page < $counter - 1)
$pagination .= "<a href=\"$targetpage$pagestring$next\">next »</a>";
else
$pagination .= "<span class=\"disabled\">next »</span>";
$pagination .= "</div>\n";
}
Just out of curiosity, try something like this:
if ($page < $lastpage - 1)
$pagination .= "<a href=\"$targetpage$pagestring$next\">next »</a>";
else
$pagination .= "<span class=\"disabled\">next »</span>";
$pagination .= "</div>\n";
}
:)
