Why does it says "KamikazeJAM108867 is not a valid member of Players"?

I have this block of code here and it takes the money perfectly but then prints this error, "KamikazeJAM108867 is not a valid member of Players" yet im playing the game. Can Someone please help me. Essentially i have a Gui with a playername and an amount, the amount works fine but it has a hard time sending the money to the right player "hence the error" Someone please help!!!

local player = game.Players.LocalPlayer
script.Parent.Send.MouseButton1Down:Connect(function()
	print("clicked send")
	local playername = script.Parent.Playername.Text
	local amount = script.Parent.Amount.Text
	if player.leaderstats.Money.Value >= tonumber(amount) then
		player.leaderstats.Money.Value = player.leaderstats.Money.Value - tonumber(amount)
		wait(2)
		game.Players(playername).leaderstats.Money.Value = game.Players(playername).leaderstats.Money.Value + tonumber(amount)
	end
	if player.leaderstats.Money.Value < tonumber(amount) then
		script.Parent.Send.Text = "Not Enough Money"
		wait(1)
		script.Parent.Send.Text = "Send"
	end
	
	
end)

Line 9. You are using brackets () instead of square brackets []. Also, the TextBox can receive any kind of text, so its Text may not be a player name. For this, use FindFirstChild.

if game:GetService('Players'):FindFirstChild(playername) then

That should work.
