Packet Spammer (Le Bot 5.4)

I am really confused now... So on the packet spammer I add the code

%xt%zm%getDrop%19457%4762% - Unidentified 13

and

%xt%zm%getDrop%115861%4862% - Voucher of Nulgath (Non Member)

So i put it into the box and hit add... Then i hit the check mark to start and set the time thingy to 2000 seconds....

I don't recieve anything... Is there a reason why?

Do the codes not work anymore?

@JamesRo do you know a solution ?

Those are just pickup packets.

OH... what does that mean? I'm confused.. can you explain it to me>?
