Next page in gui

[MateoxPL]

Hello
I have this skript
and how to make a 2 gui page if players are in {_temp} is 0

command /targ [<text>]:
    aliases: /sklep, /bazar, /rynek
    trigger:
        set {_temp} to 0
        open chest with 4 rows named "          &2&lPlayers Shop" to player
        wait 3 tick
        loop all players:
            if loop-player have permission "elite":
                if (size of {targ.itemy.%loop-player%::*}) > 0:
                    set player's current inventory's slot {_temp} to {@TargItemWeteranILegenda} named "&aTarg: &6&l%loop-player%" with lore "&8Wystawione:&7 %size of {targ.itemy.%loop-value%::*}%/27"
                    add 1 to {_temp} 
                    if {_temp} > 0:
                        set player's current inventory's slot 35 to arrow named "&6Next Page"                 
        loop all players:
            if loop-player don't have permission "elite":
                if (size of {targ.itemy.%loop-player%::*}) > 0:
                    set player's current inventory's slot {_temp} to {@TargItemGracz} named "&aTarg: &e&l%loop-player%" with lore "&8Wystawione:&7 %size of {targ.itemy.%loop-value%::*}%/27"
                    add 1 to {_temp}
                    if {_temp} > 0:
                        set player's current inventory's slot 35 to arrow named "&6Next Page"

I would use TuSKe and do it the following way:

function changePage(page: number, container: inventory, line-amount: number = 27) :: number:

  loop page {_page} of all players with {_line-amount} lines:
    add 1 to {_slot}
    set slot {_slot} - 1 of {_container} to {@TargItemWeteranILegends} named "<light green>Targ: <orange>%loop-value%" with lore "<grey>Wystawione: <light grey>%size of {targ::item-y::%loop-value%::*}%/27"
  set slot 30 of {_inventory} to "<light green>Current Page" with lore "<light grey>%{_page}%"
  return {_page}


# This belongs to your command's trigger
open chest with 4 rows named "          <green><bold>Players Shop" to player

set slots integers from 27 to 35 of player's current inventory to black glass plane
set {_start} to changePage(1, player's current inventory)

if size of all players is greater than 27:
  set slot 35 of player's current inventory to arrow named "<orange>Next Page"


on inventory click:

  display name of event-inventory contains "Players Shop"
  cancel event

  if event-slot is an arrow named "<orange>Next Page":
 
    set {_page} to changePage(({_page} + 1), event-inventory)
    set slot 27 of event-inventory to arrow named "<orange>Previous Page"
 
  else if event-slot is an arrow named "<orange>Previous Page":

    set {_page} to changePage(({_page} - 1), event-inventory)
 
    if {_page} is 1:
      set slot 30 of event-inventory to black glass pane
