Question

I have a switch built in to set variables based on a $_POST['x'];

my echo test works on all the variables but one, and i cannot seem to find out why:

switch ($jobType) {
    case "pp":
        $jobType = "Pick Pocket"; //echo works 'Pick Pocket'
        $success = rand(1,100); //echo works - random numbers 1-100
        $threshold = 0; //echo works - '0'
        $money = rand(0-100); //changed to rand(0,100) and it works
        echo $money;
        break;
}

the echos I named work both inside the case and outside the switch except for $money. Any ideas what I am missing?

UPDATED --

switching from 1-100 to 1,100 worked - thanks everyone!

Answer 1

$money = rand(0-100);

it's not 0-100 should be 0,100
