더하기 빼기가 이렇게 어려울 줄이야,,,,

기존스킨을 활용해서 약간 변경하려는데 ...

wr_8의 월별 합산 및 총계는 잘나옵니다.

그런데 wr_255도 월별 합산을 추가하려는데 잘 안되네요,,,

for문 안에 뭔가를 집어넣어줘야 할거 같은데...

도와주세요,,,

$g5['title'] = '월별 실적';
include_once('./member_count.sub.php');

$colspan = 4;

$max = 0;
$sum_count = 0;
$sql = " select SUBSTRING(wr_datetime,1,7) as vs_month, sum(wr_8) as total, sum(wr_255) as refund
            from g5_write_test
            where date(wr_datetime) between '{$fr_date}' and '{$to_date}'
            group by vs_month
            order by vs_month desc";

$result = sql_query($sql);
for ($i=0; $row=sql_fetch_array($result); $i++) {
    $arr[$row['vs_month']] = $row['total'];

    if ($row['total'] > $max) $max = $row['total'];

    $sum_count += $row['total'];

}
