PHP In RSForm ForEach

I need to run a foreach loop on the form submit of rsform pro in joomla

This is the code I have but it's only running once

foreach ($_POST['form']['Member'] as $mem)
{

$query = $db->getQuery(true);
$columns = array('EventName', 'EmployeeListType','EmployeeList','Teacher');
$values = array($db->quote($EventName), $db->quote($EmployeeListType), $db->quote($mem), $db->quote($Teacher));
$query
->insert($db->quoteName('Textes'))
->columns($db->quoteName($columns))
->values(implode(',', $values));

$db->setQuery($query);
$db->execute();
}

What do I ned to change so it runs for each loop instance?
