[SOLVED]

Maybe you can create an extra command that runs the two commands you need, then you put the extra command in [make player execute "command"]

I cant understand what you need Xd

 

It's hard to see what your code is without using the code function in Spigot Forums.

To answer your question, I would suggest the usage of the skQuery skExtension (I suggest @LimeGlass's fork for it) to format a GUI. It uses the following syntax:

Code (Text):

#conditional here
open chest with 4 rows named "{@option1}" to the player
wait 2 ticks
format slot 0 of player with {@option2} named "{@option3}" with lore "" to close then run [lambda or predicate here]

Since you want one effect to run two lambdas, I would use this:

Code (Text):

format slot... [do[make player execute command "/me Hi"]->[message "§aSuccess!"]]

 

Idk what do u want to do m8 :l

 

Can you show the code using the code function?

 

Considered making a command that runs them two commands and having them run that command in the GUI?

 

Make a command that just makes player execute others.

 

Code (Text):

command /2commands:
  trigger:
    execute console command "/example"
    execute console command "/example2"

 

This MUST work:

Code (Text):

command /twoinone:
  trigger:
    execute console command "/manudelv %player% {@suffixorprefix}"
    message "{@removemsg}"

if player has permission "{@remove}":
  format slot 40 of player with {@removetitle} named "{@removename}" with lore "{@removetitlelore}" to run [make player execute command "/rwoinone"]
 

Obviously you need Skript and SkQuery

 

You should just use set slot & inventory clicks or TuSke GUI to make guis... set format slot is a no no...
