How i can delete newFrame and replacing it with a new newFrame?

Sorry for bad english

        statWindowOpened = true
        local newFrame = FinalTemplate:Clone()
        ClickSound:Play()
        newFrame.PetPicture.Image = petImage
        newFrame.PetPicture.Species.Text = Pet.Species
        if Pet.Level < 30 then
            local barSize = Pet.Experience/MAX_EXP[Pet.Level]
            newFrame.Experience.Bar.Size = UDim2.new(barSize,0,1,0)
            newFrame.Experience.Text.Text = "EXP: " .. tostring(Pet.Experience) .. "/" .. tostring(MAX_EXP[Pet.Level])
        else
            newFrame.Experience.Bar.Size = UDim2.new(1,0,1,0)
            newFrame.Experience.Text.Text = "MAXIMUM EXP"
        end
        if Pet.Equipped then
            newFrame.Equip.Text = "UnEquip"
        else
            newFrame.Equip.Text = "Equip"
        end
        newFrame.MoneyBoost.Text = "Money +" .. tostring(math.floor((Pet.MoneyBoost*100))/100)
        newFrame.PowerBoost.Text = "Power +" .. tostring(math.floor((Pet.PowerBoost*100))/100)
        newFrame.Level.Text = "LEVEL: " .. tostring(Pet.Level)
        newFrame.Equip.Activated:Connect(function()
            local result, message = EquipPet:InvokeServer(petId)
            ShowMessage:Fire(message,result)
            if result then 
                RefreshInventory:Fire()
                statWindowOpened = false
                newFrame:Destroy()
            end
        end)    
        newFrame.Equip.MouseEnter:Connect(function()
        HoverSound:Play()
        end)
