Can you direct me to an excellent random number generator for online advertisements (Doubleclick)?

Question

I was told that I needed either a JavaScript function or a server side random number generator for a Doubleclick ad (Doubleclick prefers the server side). I'm aware that searching Google will bring up a lot of results regarding Javascript RNG code. However, I want to get this set up as soon as possible. Can anyone provide instruction on how to get this done in the easiest, yet most effective manner? Thank you so much for your time. I use Dreamweaver 8 on Windows XP, S.P. 2. The documentation that Doubleclick provided was confusing.

Answer 1

function random(lessthan){
return Math.floor (Math.random()*lessthan)
}


var randomNumberLessThanFive = random(5)

Answer 2

I can't help you in javascript. but in php:
$min=1;
$max=100;
$randomNum=rand(1,100);
?>
Cheers,
