Pytanie co do komendy

Witam,
Chciałbym stworzyć skrypt na sklep na swój serwer.

Używałem czegoś takiego:
 

        if arg-1 is "kupeq":
            if player's balance is less than 800:
                send "&cBLAD: &4nie posiadasz wystarczajaco Money !!" to player
                execute player command "money"
                stop
            else:
                give 1 diamond helmet of protection 4 and unbreaking 3 to player
                give 1 diamond chestplate of protection 4 and unbreaking 3 to player
                give 1 diamond leggings of protection 4 and unbreaking 3 to player
                give 1 diamond boots of protection 4 and unbreaking 3 to player
                remove 800 from player's balance
                send "&aPomyslnie zakupiono Set 4/3" to player
                stop

Poprosiłbym aby ktoś przerobił to pod kupno rangi coś w tym stylu tylko żeby działało.

 

        if arg-1 is "r1":
            if player's balance is less than 70000:
                send "&cBLAD: &4nie posiadasz wystarczajaco coinsow !!" to player
                execute player command "money"
                stop
            else:
                execute console command pex group evip user
                remove 300 from player's balance
                send "&aPomyslnie zakupiono Kilof 5/3/3" to player
                stop
