some of the server validations are using the validated entries bindings, the validated entries bindings only get a value of validation fails, make sure to use the form collection in your server validations, not the validated entries.
also, change:
$BurstSize = 1;
$BurstTime = 200;
$WaitTime = 1;
to:
$BurstSize = 200;
$BurstTime = 1;
$WaitTime = 1;
