Help with custom command

[pine adder]

i dont know how to input the argument while making the skript still work

  usage:  /npc <add/remove/rename/tphere> <npcname> [<type>]
  permission: server.npc
  trigger:
    if arg-1 is "add":
      spawn a %arg-3% with name at player:
        set name of the %arg-3% to "%arg-2%"```

[errant silo]

first, for that u don't need the % %

and probably should do spawn 1 arg-3 parsed as entity
