What is wrong with my skript?

[ReZ]

Trying to figure out what is wrong with my skript.
on spawn:
if player's world is "world":
givebetaprefix(player)

function givebetaprefix(p: player):
run player cmd "lp user {_p} parent set beta-testers" as op
gives me the Cant understand this condition

I believe the problem you are having is found in this line: run player cmd "lp user {_p} parent set beta-testers" as op
The correct way to do this is: execute console command "lp user %{_p}% set beta-testers"

Make sure to indent your code as well
