I want to call a function that is inside a module from a string. I'm using loadstring. Nothing happens when calling the module from inside IF/ELSE statement. But it does work when calling it from the functionReturned variable.

This is what i have in ServerScriptService

local lehModule = require(game.ServerScriptService.ModuleScript)
			local functionReturned = lehModule.checkCommand(item["Command"],item["MoreInfo"])
			if functionReturned then
				local lehString = "lehModule"..functionReturned
				if item["MoreInfo"] then
					local stuff = "(\""..tostring(item["Command"]).."\",\""..tostring(item["MoreInfo"]).."\")"
				--prints: lehModule.killPlayer("kill","Player1")
					print("lehFunc: "..lehString..stuff)
					loadstring(lehString..stuff)
				else
				--prints: lehModule.killall()
					print(lehString.."("..")")
					loadstring(lehString.."("..")")
				end
			end

and this is what i have in my module script:

local module = {}
	local commands = {["kill all"]=".killall",["tp"]=".tp",["changeTime"]=".changeTime",["kill"]=".killPlayer",["messageToPlayer"]=".messagePlayer",["messageAll"]=".messageAll"}
	function module.messageAll(msg)
		
	end
	function module.messagePlayer(msg)
		
	end
	function module.killPlayer(plr)
		local player = game.Workspace:FindFirstChild(plr)
		if player then
			player.Humanoid.Health = 0
		else
			print("inside Kill Player: ",player)
		end
	end
	function module.killall()
		for i in pairs(game.Players:GetChildren()) do
			print("killAll i: ",i)
			local player = game.Workspace:FindFirstChild(i.Name)
			if player then
				player.Character.Health = 0
			else
				print("leh I: ",i.Name)
			end
		end
		return "done"
	end
	function module.tp(info)
		local plr1 = ""
		local plr2 = ""
		local plr1Done = false
		for i in string.gmatch(info, " , ") do
			if not plr1Done then
				plr1 = i
				plr1Done = true
			else
				plr2 = i
			end
		end
		local plrWork = game.Workspace:FindFirstChild(plr1)
		local plrWork2 = game.Workspace:FindFirstChild(plr2)
		plrWork.Position = plrWork2.Position + Vector3.new(0,2,0)
	end
	function module.changeTime()
		local done = false
		local hour
		for i in string.gmatch(game.Lighting.TimeOfDay, ":") do
			if not done then
				hour = tonumber(i)
				done = true
			end
		end
		if hour > 7 and hour < 13 then --checks if time is between day and midday
			game.Lighting.TimeOfDay = "19:00:00"
		else
			game.Lighting.TimeOfDay = "07:00:00"
		end
	end
	function module.checkCommand(commandText,aditionalInfo)
		print("comm: ",commandText," moreinf: ",aditionalInfo)
		if aditionalInfo == nil or aditionalInfo == "" then
			local func = commands[commandText]
			if func then
				return func
			end
		else
			local func = commands[commandText]
			print("lehFun2", func)
			if func then
				return func
			end
		end
	end
return module

I feel like i'm just not calling it properly, since this is the first time i'm learning about and using module scripts. If you have any tips and/or useful insights, feel free to share. :)
