Request Script or help fix this one

[Keiro]

Look, the idea is, 3 players stay on a sqm, then they are tped to a quest, but if there is ppl already on the quest, then they wont be able to use the switch.

i have this script , but smth is wrong , it always enter the " if t == 0 or not isPlayer(t) then" , i noticed t is always 0, but positions are correct, i checked and re checked....so i dont understand why t keeps being 0, so that way it will keep entering that if


thanks you.
