otestat .. men borde fungera

 $sql = "SELECT COUNT(id) as antal, DATE_FORMAT(start_date, '%M %Y') as manad FROM dinTabell GROUP BY manad ORDER BY manad DESC";
$res = mysql_query($sql);
while ($svar = mysql_fetch_assoc($res)) {
    list ($year, $month) = explode(' ', $svar['manad']);
    if (isset($akt_year) && $year == $akt_year) 
        $add_year = "";
    else {
        $akt_year = $year;
        $add_year = "Year $year<br />\n";
    }
    echo "$add_year $month  {$svar['antal']} <br />\n";
}

/red. typo.. hade använt $manad istället för $month på sista raden..

TACK!
