$new_temp = "CREATE TABLE temp_collections TYPE=InnoDB SELECT * FROM upcoop.loans_outstanding WHERE loan_type_ID ='$loan_type_ID'";
$resulta = mysql_query($new_temp,$link);

$new_query = "SELECT * FROM temp_collections";
$resultb = mysql_query($new_query,$link);


while ($row = mysql_fetch_array($resultb,MYSQL_ASSOC) ){





$query = "SELECT members.members_ID, members.first_name,members.mid_name,members.last_name,
temp_collections.loan_accnt_ID,temp_collections.monthly_amornt FROM members LEFT JOIN temp_collections ON
members.members_ID = temp_collections.members_ID
WHERE temp_collections.loan_type_ID = '$row[loan_type_ID]'ORDER BY last_name";




$result = @mysql_query($query,$link);
