Dialog Script not working, not animating text????

I have a dialog system and I need it to show the player what the NPC is saying. I noticed in ROBLOX server version it yields on a variable which is called DialogGui. I have used the developer console to see what is nil and what is not. It shows up DialogGui nil. I have a module script in ReplicatedStorage, a LocalScript in StarterCharacterScripts and a ServerScript in a part.

-- Module Script -- 
local data = {}

data.warnScreen = game.ReplicatedStorage.WarnGui
data.backpackScreen = game.ReplicatedStorage.BackpackGui
data.dialogScreen = game.ReplicatedStorage.DialogGui
data.shopBlur = game.ReplicatedStorage.ShopBlur
data.tutorialScreen = game.ReplicatedStorage.TutorialGui
function data.openPageFunction(obj,pageTxt)
	print("Animating Text!")
	for i = 1,#pageTxt do
		obj.Text = string.sub(pageTxt,1,i)
		wait()
	end
end
function data.closePageFunction(obj,pageText)
	print("Animating Text")
	for i = #pageText,1,-1 do
		obj.Text = string.sub(pageText,-1,i)
		wait()
	end
end
function data.openWarning(parent,screen)
	--[[
		MainWarn Old Position: 0, 0,0.824, 0
		MainWarn New Position: 0.004, 0,1.024, 0
		KeyWarn Old Position: 0.423, 0,0.849, 0
		KeyWarn New Position: 0.427, 0,1.048, 0
	--]]
	print("Warning Open!")
	local newWarn = screen:Clone()
	local mainWarn = newWarn:WaitForChild("MainWarn")
	local keyWarn = newWarn:WaitForChild("KeyWarn")
	newWarn.Parent = parent
	mainWarn:TweenPosition(UDim2.new(0, 0,0.824, 0),"Out","Quad",1,true)
	keyWarn:TweenPosition(UDim2.new(0.423, 0,0.849, 0),"Out","Quad",1,true)
end
function data.closeWarning(screen)
	print("Warning Closed!")
	local mainWarn = screen:WaitForChild("MainWarn")
	local keyWarn = screen:WaitForChild("KeyWarn")
	mainWarn:TweenPosition(UDim2.new(0.004, 0,1.024, 0),"Out","Quad",1,true)
	keyWarn:TweenPosition(UDim2.new(0.427, 0,1.048, 0),"Out","Quad",1,true)
end
function data.changeProp(obj,walk,jump)
	obj.WalkSpeed = walk
	obj.JumpPower = jump
end
return data

Filtering Enabled is true by the way

Hello! I think that your problem is that since your game is FilteringEnabled, the server can't see the contents inside of any player's Backpack, StarterGear, or PlayerGui. To fix this, you will want to use a RemoteEvent to FireClient() to the player whose character touched. Then in a LocalScript, call the ModuleScript functions.

-- Line 14 in your script
<RemoteEvent>:FireClient(player)

-- LocalScript
<RemoteEvent>.OnClientEvent:Connect(function()
	-- Call Module functions
end)

Your name "module" could be mixing up the script. Also, you don't need wait for child. You should just map out the children normally. If it's in PlayerGui try changing the name "Module" as it can confuse the script with the module on line 3. If it's in PlayerGui try local dialogGui = playerUI.module.dialogScreen.Name and change the name of "module". Otherwise, do local dialogGui = module.dialogScreen.Name if you're referring to the module inside ReplicatedStorage defined on line 3. Try not to use WaitForChild when it's not needed and mix up the names.
