Execute command using GUI item not working!

[Dlazar]

Hello
I have a server where I use a navigator clock and skript to navigate between spawn and survival! I have the script written and it worked on an old server, however it won't work on this new one! The problem is that I have formatted GUI slots and added run commands, but when I click on the item in the menu, it doesn't run what it is supposed to! I am using TuSKe for the GUI! Any ideas on how I can make the run command actually work!
With regards,

command /menu:
    trigger:
        open virtual chest inventory with size 1 named "Menu" to player
        format gui slot 0 of player with beacon named "Spawn" to run:
            teleport player to location at 11878, 152, 5999 in world "Server_world"
            set the player's gamemode to survival
            clear the player's inventory
            set slot 8 of player to clock named "&cNavigator &7"
        format gui slot 1 of player with iron sword named "Survival" to run:
            teleport player to location at  -46, 70, -22  in world "Server_world"
            #set the player's gamemode to survival

on rightclick holding a clock:
    make player execute "menu"

on join:
    set slot 8 of player to clock named "&cNavigator &7"
on player respawn:
    set slot 8 of player to clock named "&cNavigator &7"

on inventory click:
    if clicked slot = 8:
        cancel the event
on inventory click:
    if clicked slot = 8:
        cancel the event
