When i try to print the CarModelName table in the table from GetStat it throws this error: ServerStorage.CarDataManager:27: attempt to index field '?' (a nil value). I have tried to fix it myself but couldn't.
OnCarPurchase
local CarDataManager = require(game.ServerStorage.CarDataManager)
local CarsAPI = require(game.ServerStorage.CarsAPI)
local Money --Where your money value is located
game.ReplicatedStorage.PurchaseCar.OnServerEvent:Connect(functi on(Player, CarModelName)
print(CarDataManager:GetStat(Player)[CarModelName])
end
