Help! Frame is not valid member of ScreenGui?

I'm trying to create a shop system with FE enabled and here are my scripts.

This script is in my ServerScriptService and I'm trying to use it as a bridge to the ROBLOX server to the player client.

local debounce = false
game.Workspace.Enter.Touched:Connect(function(hit)
	if not debounce then
		debounce = true
	if game.Players:GetPlayerFromCharacter(hit.Parent) then
		game.ReplicatedStorage.ShowShopGui1:FireClient(game.Players:GetPlayerFromCharacter(hit.Parent))
	end
	wait(2)
	debounce = false
	end
end)

This is my second Script which goes into my GUI that is meant to show the GUI.

game.ReplicatedStorage.ShowShopGui1.OnClientEvent:Connect(function()
	script.Parent.Frame.Visible = not script.Parent.Frame.Visible
end)

I'm sure it would also be helpful if I add the branch for the GUI, which looks like this:

WeaponShop1

LocalScript

Holder (Frame used for my GUI)
