I need help making a limit to how many people can be on a team?

i need help on making a limit on how many people can be on a team. im new to scripting and im wondering if anyone could put the code in for me so i can copy it.

i have two teams, one is labeled Murderer and one is named Innocent. i would like 1 person on each team and for it to be random on which one they get. please and thank you.

I think this is what you're looking for let me know I'll try to help.

local team1playercount = game.ReplicatedStorage.numbervalue -- name of the numbervalue
local team2playercount = game.ReplicatedStorage.numbervalue -- name of the second numbervalue 
local teamlimit1 = 1 -- change the limit to whatever
local teamlimit2 = 1 -- change the limit to whatever
game.Players.PlayerAdded:Connect(function(player)
	local team = math.random(1,2)
	if team == 1 then
		if team1playercount.Value ~= teamlimit1 then
		team1playercount.Value = team1playercount.Value + 1
	 	player.TeamColor = BrickColor.new("Really red") -- change color to the first teamcolor 
		else
			if team2playercount.Value ~= teamlimit2 then
			team1playercount.Value = team1playercount.Value + 1
		 	player.TeamColor = BrickColor.new("Really red") -- change color to the second teamcolor
			else
				print("Both teams are full!")
			end
		end	
	elseif team == 2 then
		if team2playercount.Value ~= teamlimit2 then
		team1playercount.Value = team1playercount.Value + 1
	 	player.TeamColor = BrickColor.new("Really red") -- change color to the second teamcolor
		else
			if team1playercount.Value ~= teamlimit1 then
			team1playercount.Value = team1playercount.Value + 1
		 	player.TeamColor = BrickColor.new("Really red") -- change color to the first teamcolor 
			else
				print("Both teams are full!")
end
	end
end
	end)
