How do you fix ServerStorage is not a valid member of DataMode error?

I have a problem with this script;

local button = script.Parent
local HatchingFrame = script.Parent.Parent.Parent:WaitForChild("HatchingMoment")
local HatchedImage = script.Parent.Parent:WaitForChild("HatchedImage")
local HatchedName = script.Parent.Parent:WaitForChild("Name")
local Slot1 = game.Players.LocalPlayer.PlayerGui.MenuGui.InventoryMain.InventoryFrame.InventoryBackground:WaitForChild("ElementSlot1")
local Image = game.Players.LocalPlayer.PlayerGui.MenuGui.InventoryMain.InventoryFrame.InventoryBackground.ElementSlot1:WaitForChild("ElementImage")
local amount = game.Players.LocalPlayer.PlayerGui.MenuGui.InventoryMain.InventoryFrame.InventoryBackground.ElementSlot1.ElementImage:WaitForChild("Amount")
local element = game.Players.LocalPlayer.PlayerGui.EggSellGui.MainFrame.ShopFrame.BuggyEgg:WaitForChild("Element")
local slot1currentimage = game.Players.LocalPlayer.PlayerGui.MenuGui.InventoryMain.InventoryFrame.InventoryBackground.ElementSlot1.ElementImage:WaitForChild("CurrentImage")
local purpleterriaimage = game.ServerStorage.PurpleTerria:WaitForChild("Image")
local purpleterrianame = game.ServerStorage.PurpleTerria:WaitForChild("Name")

button.MouseButton1Down:connect(function()
	if HatchingFrame.Visible == true then 
		HatchingFrame.Visible = false
		button.Visible = false
		HatchedImage.Image = ""
		HatchedName.Text = ""
		if element.Value == "Purple Terria" then
			Slot1.Visible = true
			wait(0.1)
			slot1currentimage.Value = purpleterriaimage.Value
			wait(0.1)
			Image.Image = slot1currentimage.Value
			amount:WaitForChild("NumberAmount").Value = amount:WaitForChild("NumberAmount").Value + 1
		end
	end
end)

Error says; ServerStorage is not a valid member of DataMode

So in the script this line has an error;

local purpleterriaimage = game.ServerStorage.PurpleTerria:WaitForChild("Image")

Any idea how to fix? Error on line 10, please help!
