hi guys.. need a bit of a help here.. ?
well.. first of.. ill show u the code that im workin on..

so im extracting values from a db..

[code=php] while ($row = $db->fetch()) {
$amount1 = $row[amount1];
$amount2 = $row[amount2];
$totalAmount = $amount1 + $amount2;

echo $totalAmount;
}

echo $grandTotal;[/code]

and then at the very end, after looping through all the data, i wanted to show a grand total ($grandTotal)… which is the total of $totalAmount…

so how can i do this? any suggestions? thank you..

$grandTotal = 0;
while ($row = $db->fetch()) {
$amount1 = $row[amount1];
$amount2 = $row[amount2];
$totalAmount = $amount1 + $amount2;
$grandTotal += $totalAmount;
echo $totalAmount;
}

echo $grandTotal;
[/code]

[code=php]$query = "SELECT SUM(amount1 + amount2) FROM tablename";
$grandtotal = mysql_query($query);
echo $grandtotal;[/code]
