[ISSUE SOLVED] Saving a table to a data store. How do I fix this error?
local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("dataStore")
game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player
local Cash = Instance.new("IntValue")
Cash.Name = "Cash"
Cash.Parent = leaderstats
local Wins = Instance.new("IntValue")
Wins.Name = "Wins"
Wins.Parent = leaderstats
local playerUserId = "Player_" .. player.UserId
--Load data
local data
local success, errormessage = pcall(function()
data = dataStore:GetAsync(playerUserId)
end)
if success then
print("Data successfully loaded!")
Cash.Value = data.Cash
Wins.Value = data.Wins
else
print("There was an error loading data!")
warn(errormessage)
end
end)
game.Players.PlayerRemoving:Connect(function(player)
local playerUserId = "Player_" .. player.UserId
local data = {
Cash = player.leaderstats.Cash.Value;
Wins = player.leaderstats.Wins.Value;
}
local success, errormessage = pcall(function()
dataStore:SetAsync(playerUserId, data)
end)
if success then
print("Data successfully saved!")
else
print("There was an error saving data!")
warn(errormessage)
end
end)
How do I fix this? The error is attempting to index nil with cash. I am trying to save the table to the datastore but do not know how to fix this error. I know where the error is and why there is an error, but what am I meant to do about it.

The Problom Here is that , your script nerver Creates any data at all , Its just trying to get data.
And the data it is trying to get has never benn created so lets create it like this... :
local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("dataStore")
local STARTER_CASH = 0--- Put Your Starter Amount Of Cash Here !
local STARTER_WINS = 0--- Put Your Starter Amount Of Cash Here !
game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player
local Cash = Instance.new("IntValue")
Cash.Name = "Cash"
Cash.Parent = leaderstats
local Wins = Instance.new("IntValue")
Wins.Name = "Wins"
Wins.Parent = leaderstats
local playerUserId = "Player_" .. player.UserId
--Load data
local data
local success, errormessage = pcall(function()
data = dataStore:GetAsync(playerUserId)
if not data then ----- If The Player Does not Have Any Data , then lets Create New Data for them !
local NewData = { Cash = STARTER_CASH,
Wins = STARTER_WINS}
local Made , errormsg = pcall(function()
dataStore:SetAsync(playerUserId, NewData)
end)
if Made then
print(" Created New Data For ".. player.Name .." ! :D ")
else
warn("Could Not Create Data For ".. player.Name.." ! D: Error Message : ".. errormsg)
end
end
end)
if success then
print("Data successfully loaded!")
Cash.Value = data.Cash
Wins.Value = data.Wins
else
print("There was an error loading data!")
warn(errormessage)
end
end)
And That Is How you create New Data For New Players ! :D
I also Added New Variables Called STARTER_CASH and STARTER_WINS so you can customised the amount of cash and wins a new player gets !
Good Day !
Issue solved. Just had to add an if statement to check whether data was nil, then if it was I just set the cash and wins to 0.
