    okay , thanks so much again. i tried it again ensuring i select a team or teams but no joy I'm afraid. maybe i need to add more echo's to // loop through the teams, extracting their data from the results table foreach($_POST['team'] as $team) { $teamData = getTeamData($team, $results); //.. now decide what to do with $teamData, eg show each selected teams results echo getResults($teamData) . '</br />'; }
