So I try to make people pay farm items to get one rare item

Is this right? It doest take the farm item cost from me, but i think something i got wrong with the command:

"UseCommand": true,
"CommandOnPlayer": true,
"Command": "inventory.giveto <playername> gloweyes",

"UseCommand": true,
"CommandOnPlayer": true,
"Command": "inventory.giveall gloweyes",

This works, but i only want to give it to the specifik player witch interacts with the NPC

      "UseCommand": true,
      "CommandOnPlayer": true,
      "Command": "inventory.giveto",
      "Arrangements": "gloweyes",
