Variable in module changing in one script but not the other?

I have a module script named MainModule and I am changing the value of a variable called CurrentShaggy and it is saying that the value of that variable is changed in the script that I change it in but when I use that variable in another script, it still says it was an old value.

Local Script:

s = require(workspace:WaitForChild("Modules"):WaitForChild("ShaggyModule"))
m = require(workspace:WaitForChild("Modules"):WaitForChild("MainModule"))
player = game:GetService("Players").LocalPlayer
char = workspace:FindFirstChild(player.Name)
script.Parent.MouseButton1Click:Connect(function()
	if s[m.Shop_Selected].owned then
		warn("Equip button has not been set up yet")
	else
		local leaderstats = player:FindFirstChild("leaderstats")
		local cash = leaderstats:FindFirstChild("Cash")
	
		if cash.Value >= s[m.Shop_Selected].cost then
			cash.Value = cash.Value - s[m.Shop_Selected].cost
			s[m.Shop_Selected].owned = true
			char:FindFirstChild(m.CurrentShaggy).Name = m.Shop_Selected
			m.CurrentShaggy = m.Shop_Selected
			print(m.CurrentShaggy) -- Prints correct thing but not changing in other scripts
			char:FindFirstChild(m.CurrentShaggy).Handle.Mesh.TextureId = "rbxassetid://"..s[m.CurrentShaggy].textureId
			print("Item succefully bought")
			script.Parent.Parent.Parent.Parent.Parent.Parent.Visible = false
		end		
	end
end)

Server Script:

size = game:GetService("ReplicatedStorage"):WaitForChild("Remotes"):WaitForChild("SizeUp")
m = require(workspace:WaitForChild("Modules"):WaitForChild("MainModule"))
s = require(workspace:WaitForChild("Modules"):WaitForChild("ShaggyModule"))
Math = require(workspace:WaitForChild("Modules"):WaitForChild("MathModule"))

debounce = true
DELAY = .1

size.OnServerEvent:Connect(function(player)
	if debounce then
		debounce = false
		local char = workspace:FindFirstChild(player.Name)
		local hat = char:FindFirstChild(m.CurrentShaggy)
		local mesh = hat.Handle.Mesh
		local scaleAmount = s[m.CurrentShaggy].sizepc
		local chance = s[m.CurrentShaggy].gemChance
		
		if Math.RandomPercent(chance) then
			player.leaderstats.Gems.Value = player.leaderstats.Gems.Value + 1
			m.Gems = m.Gems + 1
			print("You got a gem!")
		end
		
		mesh.Scale = mesh.Scale + Vector3.new(scaleAmount,scaleAmount,scaleAmount)
		player.leaderstats.HatSize.Value = Math.Round(mesh.Scale.X,2)
		m.HatSize = player.leaderstats.HatSize.Value
		player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + s[m.CurrentShaggy].moneypc
		m.Cash = m.Cash +  s[m.CurrentShaggy].moneypc		
		wait(DELAY)
		debounce = true
	end
end)

If you change the value from a local script, the value changes only locally for this particular player, so you'll need to use a remote event and server script to solve this problem
