Calling Module function from a Local script?

Hey guys, having an issue trying to call a function from a Module script in a local script.

Module Script:

function Settings.Update_Gui(Ammo, StoredAmmo)
	if Settings.Gui and Settings.CanUpdateGui then
		Settings.Gui.Frame.AmmoDisplay.Text = Ammo .. "|" .. StoredAmmo --Line 77
	end
end

Local Script:

local Ammo = script.Ammo -- NumberValue
local StoredAmmo = script.StoredAmmo -- NumberValue

Settings.Update_Gui(Ammo.Value, StoredAmmo.Value)

Error: Players.Player1.Backpack.M1911.Settings:77: attempt to concatenate local 'StoredAmmo' (a nil value)

Let me know if you can figure out why I am getting this odd error or if you need a bit more information.

Thanks.

I was having this problem myself. It seems that the passed-in arguments get disordered for some reason. I resolved it by passing them in as a tuple instead and then parsing it. In your case I would do the following:

function Settings.Update_Gui(...)
	local tuple = {...}
	local Ammo = tuple[1]
	local StoredAmmo = tuple[2]
	if Ammo and StoredAmmo then
	    if Settings.Gui and Settings.CanUpdateGui then
	        Settings.Gui.Frame.AmmoDisplay.Text = Ammo .. "|" .. StoredAmmo
	    end
	end
end

And you don't have to change your localscript call.

Well, your first error is that ModuleScripts cannot be called by LocalScripts. Use a ServerScript to use a ModuleScript.

Your second error is that you're not waiting for the children of the script to exist, so:

local StoredAmmo = script:WaitForChild("StoredAmmo")
