Convert to module application- AngularJS module dependency

Question

I started to remodel my AngularJS (fully working) page to modular version.

I grouped my files to 4 modules:

-band
-user
-layout
-core

And main app.js with:

(function () {
    angular.module('zt', [

        // shared modules

        'zt.core',

        'zt.user',
        'zt.band',
        'zt.layout'

        // other modules will be lazy-loaded from router
    ]);
})();

Each module has it own controllers, services etc. and own module config file:

(function() {
    'use strict';

    angular.module('zt.user', []);
})();

And own route file:

(function () {
    'use strict';
angular.module('zt.user')
    .config(function ($stateProvider, $urlRouterProvider, $locationProvider, AccessLevels) {

        $stateProvider
            .state('app.user', {
                abstract: true,
                template: '<ui-view/>',
                data: {
                    access: AccessLevels.user
                }
            })

AccessLevels is inside zt.core module and it is simple constant:

(function() {
    "use strict";

    angular.module('zt.core')

        .constant('AccessLevels', {
            anon: 0,
            user: 1,
            mode: 2,
            admn: 3,
            suad: 4
        })

...

When I try to load page I've got an error:

Uncaught Error: [$injector:modulerr] Failed to instantiate module zt due to: Error: [$injector:modulerr] Failed to instantiate module zt.user due to: Error: [$injector:unpr] Unknown provider: AccessLevels

All files are included ok

(also the same error in zt.band module) All typing and including are ok.

When I add AccessLevels manual to zt.band and zt.user route configs another strange errors appears:

Error: [$injector:unpr] Unknown provider: ztPlayerProvider <- ztPlayer <- soundManagerDirective

and:

Error: [$injector:unpr] Unknown provider: AuthServiceProvider <- AuthService <- ApplicationControler

ztPlayer is service in the same module zt.layout with soundManagerDirective !

and AuthService is inside shared zt.core module so it should be availiable inside ApplicationController inside zt.layouts module.

My include paths near end of the body tag:

I've tried a lot of things but nothing worked! I can't figure what is the problem of this.

Thanks!
