[Resolved] Random # help

[cmptrwhz]

Hi All,

I need help with the following..

I want to generate a random number on my price quote page, then carry it through to the results page. I will also give the user the option to go back to the quote page and run another quote.

My issue is this: I can generate the random number fine the first time the user visits but I don't want it to change if they run another quote. I read somewhere that if I use "if (!$random variable)" The system will check to see if it is already set, but I don't know what else to put in there.

Thanks in advance.

Mike

if(!isset($_POST['somevar'])) {
   $my_rand = rand();
} else {
    $my_rand = $_POST['somevar'];
}
