For some reason this script says "Attempting to index a nil value", How would I fix this?
.I am making a shop gui for a game and I made a simple button that detects whether or not the player has enough money when they try to purchase an item, and if they do it gives them they item and subtracts the money from their account. The script is very basic but it gives me an error code saying "Attempting to index local "player" (a nil value).
script.Parent.MouseButton1Click:connect(function(player)
local lstats = player:WaitForChild('leaderstats')
if lstats.Tokens.Value >= 60 then
lstats.Tokens.Value = lstats.Tokens.Value - 60
else
script.Parent.Text = 'Insufficient Funds!'
end
end)
I'm tried doing it in both local and global scripts and added a wait feature but neither worked, how would I get this to work in a local script?

The reason that your script broke is that player is not a parameter to the RobloxScriptSignal [event] MouseButton1Click. If this is in a local script, which it should be, because all scripts that work in the PlayerGui, or StarterGui must be LocalScripts due to FilteringEnabled then you would try this method:
local player = game.Players.LocalPlayer
script.Parent.MouseButton1Click:connect(function()
local lstats = player:WaitForChild('leaderstats')
if lstats.Tokens.Value >= 60 then
lstats.Tokens.Value = lstats.Tokens.Value - 60
else
script.Parent.Text = 'Insufficient Funds!'
end
end)
But that probably won't work online because of FIltering Enabled. Your best bet is to use this method of using RemoteFunctions
This is how to use the recommended method
Step 1: put a RemoteFunction in the ReplicatedStorage named HandleTransaction
Step 2: Put these in your game
Replace your script with this LocalScript and put it in the same place.
local player = game.Players.LocalPlayer
local rf = game.ReplicatedStorage:WaitForChild("HandleTransaction")
script.Parent.MouseButton1Click:Connect(function()
local transaction = rf:InvokeServer()
if not transaction then
script.Parent.Text = 'Insufficient Funds!'
end
end)
Insert a Script inside the ServerScriptStorage
local rf = game.ReplicatedStorage:WaitForChild("HandleTransaction")
function re.OnServerInvoke(player)
if player:FindFirstChild("leaderstats") and player.leaderstats:FindFirstChild("Tokens")
then
if player.leaderstats.Tokens.Value >= 60 then
player.leaderstats.Tokens.Value = player.leaderstats.Tokens.Value - 60
-- if you want something to happen as a result of the transaction, like giving the player an item, put the code here.
return true
else
return false
end
end
end
