Mine Tiers

[CzechSmazal]

So im making a RPG server and im making mines. I need a command that the player can execute only once

this is my code:
command /minetier buy:
permission: skript.minebuy1
trigger:
if {_hasBought::%uuid of player%} is not set:
if player's balance >= 10000:
remove 10000 from player's balance
execute console command "lp user %player% parent add mine1"
set {_hasBought::%uuid of player%} to true
send "Byl zakoupen Mine Tier 1!"
else:
send "Nemáš dostatek peněz na zakoupení Mine Tier 1."

Yeah, this won't work because you're using a local variable (variable name prefixed with an underscore) which gets deleted immediately after the event ends.
You can use a global variable but it will take up a lot of space in your variables.csv as its a unique variable for EVERY player, and since I assume you don't want to use a RAM variable (because then they'll be able to do the command again every time the server restarts) you have a couple options.

You can check if their luckperms group is mine1 (or a group above it)
You can use a metadata tag
You can give the command a ridiculously long cooldown
