I really hate to ask I basic question to alot of you guys, but I just can't figure it out. On my website [a href=\"http://www.davevollmer.com\" target=\"_blank\"]www.davevollmer.com[/a] I would like to add the Block Time column and display the figure as "Total Time" in a box centered right above the table.

Here is what I have now

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]
// Execute SQL query
$query = "SELECT IDPIREP, CreatedOn, IDPilot, PilotName, Airline, FlightNumber, OriginAirport, DestinationAirport, BlockTime, DistanceFlight, FlightFuel FROM pirep ORDER BY CreatedON DESC";
$result = mysql_query($query) or die("SQL query failed.");

if (mysql_num_rows($result) == 0) die("There are currently no PIREPs available.");

?>

What field type is the Blocktime field? And what kind of data does it hold? If it where just numbers it would be a simple...
SELECT SUM(Blocktime) AS totaltime FROM tbl;
But it sounds to me like you have some sort of timestamp in this field.

Well, VARCHAR is of absolutley no use here. You cant sum up strings. If you can, change the field to some sort of numeric type eg INT. Then you can simply follow my example above.
