Using variables from function return

[Black_Eyes]

I would like to stop the skript if a permission is negative, but I don't know how to check a value from a function return
Her's the code, the real code is more complicated, but I let only the important things, to let you understand it. That's why you could thing that I don't have to use functions for that

function NoPerm(perm: text, p: player) :: text:
   {_p} does not have permission {_perm}:
       set {_message} to "you don't have permission %{_perm}%"
       message coloured {_message} to {_p}
       return {_message}

command /tp [<player>]:
   aliases: /tele, /tp2p, /teleport
   trigger:
       NoPerm("essentials.tp", sender)
      {_message} is set:
           stop
      teleport player to arg 1

It doesn't work, of wourse, but I don't know why^^

I already helped him on the Skript-chat Discord but I'll write the solution here anyways.

You just have to save the returned value of the function in a variable or check it directly:

if NoPerm("essentials.tp", sender) is set:

Or:

set {_message} to NoPerm("essentials.tp", sender)
If {_message} is set:

Will work.
