hello, when I use the command setbalance <player name or id *> <amount> , the balance goes to zero instead of adding money... is there an error in my order?
for example: setbalance tomy shelby 10000 resets tomy shelby's balance to zero

It would default to zero since you are specifying "shelby" as the 2nd argument, not 10000.

Correct usage for names with spaces: setbalance "tomy shelby" 10000
