vk011 on "ReferenceError: jQuery is not defined"

I keep getting this error.

I just have my plugin installed on my WP site which calls some .js files with jquery and jquery-ui-core as dependencies.

I call them like so:

wp_enqueue_script(
            'vkrwpsprojs',
            plugins_url( '/js/vkrwpsprojs.js', __FILE__ ),
            array( 'jquery' )
        );

        wp_enqueue_script(
            'fancybox',
            plugins_url( '/js/jquery.fancybox.js', __FILE__ ),
            array( 'jquery-ui-core' )
        );

The head sections of my page ( where the .js files start to get includes ) looks like so:

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js?ver=4.0" type="text/javascript"></script>
    <script src="http://l/demorwpspro/wp-includes/js/jquery/jquery.js?ver=1.11.1" type="text/javascript"></script>
    <script src="http://l/demorwpspro/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.2.1" type="text/javascript"></script>

Is the problem that jquery-ui is called before jquery? If so, how to make jquery appear before jquery-ui? The ordering that exists now shoud include jquery first and then jquery-ui, but it's not.
