Help with checking how much things are in a table

Hey there,
So I have this script here that inserts a players name into a table and I was wondering how I can check when there is 2 names in the table and then stop it from letting any other names in the table?

Here is my script:

local sign = script.Parent.Parent
local Gplrs = {}

sign.Touched:Connect(function(touching)
	if touching and touching.Parent and touching.Parent:FindFirstChild("Humanoid") then -- checks if player
		local plr = game:GetService("Players"):GetPlayerFromCharacter(touching.Parent)
		Gplrs[#Gplrs+1] = plr.Name
		print(Gplrs[1])
	end
end)
#2 
local sign = script.Parent.Parent
local Gplrs = {}
local Duplicates = {}

sign.Touched:Connect(function(touching)
	if touching and touching.Parent and touching.Parent:FindFirstChild("Humanoid") then -- checks if player
        
		local plr = game:GetService("Players"):GetPlayerFromCharacter(touching.Parent)
        if Duplicates[plr.Name] then return end
		Gplrs[#Gplrs+1] = plr.Name
        Duplicates[plr.Name] = true
		print(Gplrs[1])
	end
end)

I’m not sure about your use case here, but you might want to connect to PlayerRemoving and remove their name from the table.

It works, Thank you so much :slight_smile:

I know this is solved, but you should look into table.insert() and table.find() in the future and you won’t need to double your memory usage.

Thanks for your suggestion Ill try them out. Do you have any idea how to check how many names are in the table and then if there are 2 stop others from being added to the table.

#6 
if not #Gplrs > 2 then --If Gplrs is not smaller than 2 or in other words is 2 or above
   return
else
   table.insert(Gplrs, plr.Name) --Inserts player name in table
end
