JS not added to head loaded and phtml not loaded

Question

I am creating a very simple custom module to display an inline popup in my store.

The problem is that the my additional JS doesn't seem to be added, and the phtml file is not loaded. Both are in newsletterpopup.xml.

What am I missing?

\app\etc\modules\Mav_NewsletterPopUp.xml

<?xml version="1.0" ?>
<config>
      <modules>
            <Mav_NewsletterPopUp>
                  <active>true</active>
                  <codePool>local</codePool>
            </Mav_NewsletterPopUp>
      </modules>
</config>

\app\code\local\Mav\NewsletterPopUp\etc\config.xml

<?xml version="1.0" ?>

<config>
      <modules>
            <Mav_NewsletterPopUp>
                  <version>0.0.1</version>
            </Mav_NewsletterPopUp>
      <modules>
      <frontend>
            <layout>
                  <updates>
                        <newsletterpopup>
                              <file>newsletterpopup.xml</file>
                        </newsletterpopup>
                  </updates>
            </layout>
      </frontend>
</config>

\app\design\frontend\MY_THEME_HERE\default\layout\newsletterpopup.xml

<?xml version="1.0" ?>
<layout version="0.1.0">
    <default>
        <reference name="head">
            <action method="addJs"><script>mav/cookie/jquery.cookie.js</script></action>
        </reference>
        <reference name="before_body_end">
            <block type="core/template" name="newsletter_popup" as="newsletter_popup" template="mav/newsletter-popup.phtml" />
        </reference>
    </default>
</layout>

\app\design\frontend\MY_THEME_HERE\default\template\mav\newsletter-popup.phtml

<!-- HTML for popup shall appear here -->

\js\mav\cookie\jquery.cookie.js

I think there is problem with closing tag of </modules> can you update xml with added closing tag

<config>
      <modules>
            <Mav_NewsletterPopUp>
                  <version>0.0.1</version>
            </Mav_NewsletterPopUp>
      </modules>
      <frontend>
            <layout>
                  <updates>
                        <newsletterpopup>
                              <file>newsletterpopup.xml</file>
                        </newsletterpopup>
                  </updates>
            </layout>
      </frontend>
</config>
