can variable be removed??

[dr_overload]

I think I'm losing a variable somewhere within my code, can anyone help.

Setting variable $random

//check code
$random = rand(10001,99999);
$code = $_POST['code'];
if ($random != $code)
{
header('location: http://**.com/newsletter/error.php');
exit();
}

further down page within the signup form I am trying to display $random, but it's just blank. This is code i'm using, just simply echo.

echo $random;

Does anyone have any ideas as to why it seems I'm losing the $random.

Thanks

Jon

We'd have to see your code, btw have you checked the value of $random as soon as it is assigned a value?? That might give you an idea of what's going on. If not, then something between the two pieces of code you provided is causing the error.

A bit off-topic.. mt_rand(); is recommended instead of rand();.

A couple possibilities:

You might want to double check any comparisons you do with the variable, and make sure you're not accidentally assigning with "=" instead of comparing with "==", thereby changing the value of the variable.

If the assignment is being done within a function definition, or if the later check is within a function, then the variable may be out of scope.
