DateAdd Help

[urbandsigns.com]

I made a flash AutoX game (http://www.gdub.net/games.php). At the end it sends the lap time & number of cones hit to a php page that takes the information, records it in a MySQL database, and posts the scores. The problem is I have to add the lap time + 1 second for each cone. I did some research and found the DateAdd function which in theroy should work, but it doesn't. Below is my code, everything works except the $total2 section with the DateAdd function:

[code]<?
$name = $_GET["name"];
$score = $_GET["score"];
$cones = $_GET["cones"];
$minutes = $_GET["minutes"];
$seconds = $_GET["seconds"];
$milli = $_GET["milli"];
$total = $seconds + $cones - 1;
$total2 = DateAdd('s', $_GET["cones"], $_GET["score"]);
$result = mysql_query("INSERT INTO ***** (name, score, cones, date, total, total2) VALUES ('$name','$score','$cones',Now(),'$minutes:$total:$milli','$total2')") or die(mysql_error());
?>[/code]

Have you defined the DateAdd() function anywhere in your program
as far as I am aware there is no pre-defined function of that name in PHP.

No I didn't, I assumed DateAdd was a PHP function. Guess I better look into it more.

I have no idea what these data represent, by MySQL can do a fair bit of date math for you.
