Send money GUI does not change values on server side. Any idea?

Player money values stores at ServerStorage.PlayerMoney folder with player names inside.

I tried both remote event and function. Both prints true values to output but changes not effects server side values.

This is local script

script.Parent.MouseButton1Click:Connect(function()
	local receiver = script.Parent.Parent._02receiverplayer.Text
	local amaount = script.Parent.Parent._03amaount.Text
	game.ReplicatedStorage.sendmoney:InvokeServer(receiver,amaount)
end)

This is script inside ServerScriptService

game.ReplicatedStorage.sendmoney.OnServerInvoke = function(player, receiver, amaount)
	local receiverCheck = game.ServerStorage.PlayerMoney:FindFirstChild(receiver)
	if receiverCheck == nil then
		print("Receiver name invalid")
	elseif player.Name == receiver then
		print("You cant send money to yourself")
	else
		local totalplayermoney = game.ServerStorage.PlayerMoney[player.Name].Value
		print(player.Name.." "..totalplayermoney) --prints correct values
		local receiversmoney = game.ServerStorage.PlayerMoney[receiver].Value
		print(receiver.." "..receiversmoney) --prints correct values
		if totalplayermoney > amaount then
			totalplayermoney = totalplayermoney - amaount
			receiversmoney = receiversmoney + amaount
			print("transfer made")
			print(player.Name.." new sender money = "..totalplayermoney) --prints correct values
			print(receiver.." new receiver money = "..receiversmoney) --prints correct values
		end
	end
	
end

Thanks for your help.

i removed if statements from server script and i didnt use variables and it works now. i dont know why.

new server script:

game:GetService("ServerScriptService")

game.ReplicatedStorage.sendmoney.OnServerInvoke = function(player, receiver, amaount)
	
game.ServerStorage.PlayerMoney[player.Name].Value = game.ServerStorage.PlayerMoney[player.Name].Value - amaount

game.ServerStorage.PlayerMoney[receiver].Value = game.ServerStorage.PlayerMoney[receiver].Value + amaount

end
