Prefix GUI [skript}

In the first image you can see that I change my prefix and it changes in chat, The second image is of the Gui. The books change your prefix, and the nametag removes it.

set {rank::*} to "&6Owner", "&4Head Admin", "&cAdmin", "&bHead Builder", "&1Builder", "&aHead Mod", "&2Mod", "&eHelper", "&9Trainee", "&cYou&ftube", "&5dextromethorphan", "&1ketamine", "&7Member"
  set {rankp::*} to "owner", "srmanager", "manager", "head admin", "admin", "head builder", "builder", "head mod", "mod", "helper", "trainee", "youtube", "dextromethorphan", "ketamine", "member"

You need to change the list of {rank::*} to what you want to show up with colorcodes, the {rankp::*} does not have colorcodes but it is the permission you need to give the user to use that book, eg for youtube rank you need to give the user

youtube.prefix

after we do that next we need to go down a bit to our function

function prefixGUI(p: player):
  set metadata tag "prefix" of {_p} to chest inventory with 4 rows named "&eRanks"
  set {_slot} to 0
  loop 13 times:

change that loop 13 times to the ammount of ranks you want to show up in the Gui

if you do all that correctly it should work
