How to receive the correct value from a module script

I’m trying to get the Total number by adding the price to the total value in a module script, though the addition of price is not recorded and I always end up with zero being outputted in the script. How do I send the Total variable to the script.
My test price is set to 5 so It should be outputting 5 not 0

I have a script in workspace with this code inside:

local system = {}

		Scanner.Touched:Connect(function(Hit)
			if Hit.Parent:FindFirstChild("Price") and Hit.Parent.Parent.Name == Player.Name and Plr.Value ~= "" then
			module.scanItem(Hit,Scanner,Total,System,TILLNUMBER)
				print(Total)
			end
		end)
return system

and in the module script in SSS:

local module = require(game.ServerScriptService.ModuleScript)

system.scanItem = function(Hit,Scanner,Total,System,TILLNUMBER)
	local price = Hit.Parent:FindFirstChild("Price").Value
	Total = Total+price

	return(Total)
end

You need to say

local Total = module.scanItem(…)

In the first script
