Help on making a money transfer system?
I've been trying to make a money transfer system for my game, but everything I've tried always gets this error: "Argument 1 missing or nil." This is the script firing the remote event.
receiver = script.Parent.Receiver.Text
amount = script.Parent.Amount2Send.Text
amount2send = tonumber(amount)
sendButton = script.Parent.Send
plrName = game.Players.LocalPlayer.UserId
sendButton.MouseButton1Click:Connect(function()
game.ReplicatedStorage.BankTransfer:FireServer(amount2send, receiver, plrName)
end)
script.Parent.Close.MouseButton1Click:Connect(function()
script.Parent.Visible = false
end)
This is the serverscript.
game.ReplicatedStorage.BankTransfer.OnServerEvent:Connect(function(amount2send, receiver, plrName, plr)
local sender = plrName
local receiverID = game.Players:GetPlayerByUserId(receiver)
local amount = amount2send
if plr.Wallet.Value >= amount then
plr.Wallet.Value = plr.Wallet.Value - amount
receiverID.Wallet.Value = receiverID.Wallet.Value + amount
end
end)

One issue I noticed right of the bat is .OnServerEvent's first argument is the player instance for the player that fired the event.
RBXScriptSignal OnServerEvent ( Instance player , Tuple arguments )
Another thing is that if the string cannot be converted to a number, tonumber(string) will return nil, so I would add a check to make sure amount2send is not nil.
game.ReplicatedStorage.BankTransfer.OnServerEvent:Connect(function(plr, amount2send, receiver, plrName) -- changed the order of the arguments
if amount2send == nil then warn("Amount is nil") return end -- Exit the function to prevent error
local sender = plrName
local receiverID = game.Players:GetPlayerByUserId(receiver)
local amount = amount2send
if plr.Wallet.Value >= amount then
plr.Wallet.Value = plr.Wallet.Value - amount
receiverID.Wallet.Value = receiverID.Wallet.Value + amount
end
end)
