ServerScriptService.Game:2249: attempt to perform arithmetic (div) on nil and number?

can somebody explain problem i got on 2249 code (marked it)

                                    local divide = 1
                if hum.Parent:FindFirstChild("IsArmor") then
                    divide = 3
                elseif hum:FindFirstChild("IsJugg") then
                    divide = 7
                end                  
--2249--            if hum.Health > Config.damage / divide * 2 then
