Счетчик не работает должным образом

Я в основном создаю календарь, в котором я хочу показать посещаемость студентов. Если студент present или же absent тогда счетчик должен увеличиться до +1 соответственно. Но проблема в том, что если где-то посещаемость в календарной дате не записывается, то счетчик не может увеличить значение present или же absent,

Это код:

$present_sids = explode(",",$a['present_sids']);
$absent_sids = explode(",",$a['absent_sids']);
$leave_sids = explode(",",$a['leave_sids']);

if ($a['att_date'] == "1")

elseif (in_array($sid,$absent_sids))
{
$red_green_1 = 'ff8b70';
$absent_counter = '1';
if (in_array($sid,$leave_sids))
{
$l_1 = ' (L)';
}
else
{
$l_1 = '';
}
}
}

if ($a['att_date'] == "2")

}
elseif (in_array($sid,$absent_sids))
{
$red_green_2 = 'ff8b70';
$absent_counter = $absent_counter+1;
if (in_array($sid,$leave_sids))
{
$l_2 = ' (L)';

else
