Problem z skryptem na premiumcase'y

Witam, mam problem z skryptem, na którym nie można dostać premium case'a z komendy...

command /premiumcase [<player>] [<text>]:
 permission: sc.premiumcase
 trigger:
  if arg 1 is not set:
   if arg 2 is not set:
    send "{@tag} &8/&cpremiumcase &c[&eNick&8] [&eIlosc&8]"
  if arg 1 is set:
   if arg 2 is set:
    execute console command "give %arg 1% chest %arg 2%  name:&8[&b&l1PremiumCase&8]"
    send "{@tag} &a&lOtrzymales &4&lPremium &4&lCase &7&lx&c&l%arg 2% &a&l!" to player-arg

Na konsoli mi wtedy wyświetla się:

[11:34:15 INFO]: CONSOLE issued server command: /give MinecraftMaroYT chest 1 name:[1PremiumCase]

[11:34:15 INFO]: Błąd: Invalid key. Must be [a-z0-9/._-]:
