Operations with #GetChildren()?

Here's a question, can I perform operations with number of values returned by a table? My thought is to make a simple voting system that checks the number of votes against the number of players until it reaches a 2/3 majority. For some reason though this checking script causes the entire place to lock up when it runs. I think it's to do with dividing by the #pls number.

function update(child)
	local votes = script:WaitForChild("Votes").Value
	if child.Name == "Votes" then return 
	else
		votes = votes + 1
	end
	
	local pls = game.Players:GetChildren() -- pt. 2 of the problem
		
	if (votes / #pls) > 0.6 then -- I think this line is the problem
		local new = game.ServerStorage.Ball:Clone()
		if game.Workspace:FindFirstChild("Ball") then
			game.Workspace.Ball:Destroy()
		end
		new.Parent = game.Workspace
		new.Position = Vector3.new(-49, 17.4, 27.034)
		
		script:ClearAllChildren()
		wait()
		
		local vt = Instance.new("IntValue")
		vt.Name = "Votes"
		vt.Parent = script
	end
end

script.ChildAdded:connect(update)

Of course you can!

The problem is the way you are counting the vote total, I think. After getting any single vote, you never actually increment the total. Save votes back out to script.Votes.Value.

But eliminate the "Votes" object, really. Just use a variable! It's much cleaner and simpler.

local votes = 0;

function update(child)
	votes = votes + 1
	local pls = game.Players:GetChildren() -- pt. 2 of the problem
	if (votes / #pls) > 0.6 then -- I think this line is the problem
		local new = game.ServerStorage.Ball:Clone()
		if game.Workspace:FindFirstChild("Ball") then
			game.Workspace.Ball:Destroy()
		end
		new.Parent = game.Workspace
		new.Position = Vector3.new(-49, 17.4, 27.034)
		script:ClearAllChildren()
		wait()
		votes = 0;
	end
end

script.ChildAdded:connect(update)

You really should probably find something better than ChildAdded, but that works.
