| [Mad City] Give Widowmaker Vehicle

for i,v in pairs(game:GetService("ReplicatedStorage").ItemDatabase.Vehicles:GetChildren()) do
   local a = require(v.Data)
   for i2,v2 in pairs(a) do
       if a.Price == 0 then
           game.ReplicatedStorage.RemoteFunction:InvokeServer("BuyItem", ""..v.Name.."")
       end
   end
end

You could've used tostring. game.ReplicatedStorage.RemoteFunction:InvokeServer("BuyItem", tostring(v))
