LuaScriptException: [string "chunk"]:3: attempt to index a global 'Test' (a nil value)

[ZachHofmeister]

I'm having a problem accessing a function from a C# script through lua. This is the error given when the Lua script is run. Here is the function that runs the lua script:

`void RunPlayerScript () {
if (fileManager.activeFile != "") {
source = File.ReadAllText (Application.persistentDataPath + "/" + fileManager.activeFile + ".lua");

        env = new Lua ();
        env.LoadCLRPackage ();
        
        try {
            env.DoString (source);
        } catch (NLua.Exceptions.LuaException e) {
            Debug.LogError (FormatException (e), gameObject);
        }
        //Call ("");
    }
}`

Here is the Lua script being run:

import 'Piloting.Navigation'

Navigation.Test()

And here is the script containing the function being run from the Lua:

using UnityEngine;

namespace Piloting.Navigation {
    public static class Navigation {
        public static void Test () {
            Debug.Log ("Hello World!");
        }
    }
}

Anyone have any idea what is going wrong? Thanks!
