            local tag = character.Humanoid:FindFirstChild("creator")

            if tag ~= nil then
                local Award = 10
                local player = tag.Value

                local leaderstats = player:WaitForChild("leaderstats")
                leaderstats.Cash.Value = leaderstats.Cash.Value + Award
