How do I fix this problem with my Queue Teleport Script?

Problem

Players are not being teleported when your condition is met.

Solution

The first thing I noticed is you have an event inside of the same event. Don't do this.

Next, if you don't give the Teleport method a player object to teleport, nothing will happen to the player. (In the code below, I changed the method to TeleportPartyAsync)

The last thing is how you are incrementing the player_count variable. You have not confirmed that the 'hit' part is a descendant (or child) of the player's character.

Code

local players_service = game:GetService("Players")
local ts = game:GetService("TeleportService")
players_touching = {}

workspace:WaitForChild("Part").Touched:Connect(function(hit)
	local player = players_service:GetPlayerFromCharacter(hit.Parent)
	if player ~= nil then
		if table.find(players_touching,player) then
			table.insert(players_touching,player)
			if #players_touching >= 2 then
				ts:TeleportPartyAsync(7586111845,players_touching)
				players_touching = {}
			end	
		end
	end
end)

workspace:WaitForChild("Part").TouchEnded:Connect(function(hit)
	local player = players_service:GetPlayerFromCharacter(hit.Parent)
	if player ~= nil then
		local index = table.find(players_touching,player)
		if index ~= nil then
			table.remove(players_touching,index)
		end
	end
end)

players_service.PlayerRemoving:Connect(function(player)
	local index = table.find(players_touching,player)
	if index ~= nil then
		table.remove(players_touching,index)
	end
end)

I added 2 new events. The PlayerRemoving event which fires when a player leaves the game, and the TouchEnded event which fires when a BasePart stops touching another BasePart. When the player is no longer touching the part, we want to prevent them from being included in the teleport.

I also changed the 'player_count' variable which was a number to the 'players_touching' variable which is now a table that stores the player object value for each player we plan on teleporting.
