Oh, there's no confusion at all. The issue with this is that there are a few values that were set as undefined, rather than numerical values on the confirm.php page:
$BurstSize = undefined;
$BurstTime = undefined;
$WaitTime = undefined;
If you change these to this:
$BurstSize = 200;
$BurstTime = 1;
$WaitTime = 1;
the issue should be resolved.
