format gui slot doesnt work

[ferro31]

I tried making a menu, and when i try to foram a gui slot, it shows an error.
error:

code:

command /gui:
trigger:
open virtual chest inventory with size 3 named "&4Parkour menu" to player
format gui slot 0 of player with stone named "&6Easy parkour!" to run:
send message "a" to player
close player's inventory​

 

[yea rite]

i dont think you need the "gui" inbetween format and slot
(also vanilla gui better)

Are you sure youre doing it correctly? heres how i do it

command /guicommand:
  permission: your.permission
  trigger:
    set {_gui} to chest inventory with 3 rows named "GUI Name"
    set slot 0 of {_gui} to item named "name" with lore "lore" and "lore line 2"

You can also fill a gui if you want

command /guicommand:
  permission: your.permission
  trigger:
    set {_gui} to chest inventory with 3 rows named "GUI Name"
    loop integers between 0 and 26:
      set slot loop-number of {_gui} to gray stained glass pane named "%loop-number%"

the name of the glass pane will be the gui slot number
You can also fill a gui, then set individual slots to speed up the process of making the backround stuff

command /guicommand:
  permission: your.permission
  trigger:
    set {_gui} to chest inventory with 3 rows named "GUI Name"
    loop integers between 0 and 26:
      set slot loop-number of {_gui} to gray stained glass pane named "%loop-number%"
    set slot 4 of {_gui} to diamond sword named "blue stick"
