Why won't my module show up in my joomla web site?

I created a footer module that I want to appear at the bottom of my webpage. If I assign the footer module to the "footer-contractor" position it won't appear on the webpage. If I assign it to the "start-blankpage" position it will show up. Why won't the footer module show up when it's assigned to the "footer-contractor" position?  Thanks. Here is the code to my index.php template page:

<div id="wrapper-blankpage">
     <jdoc:include type="modules" name="start-blankpage" style="xhtml" />
       <jdoc:include type="component" style="xhtml" />
     <div id="footer_contractor"><jdoc:include type="modules" name="footer-contractor" style="xhtml" /></div>

Here is the code to the TemplateDetails.xml file:

      <files>
            <filename>index.php</filename>
            <filename>templateDetails.xml</filename>
            <filename>template_thumbnail.png</filename>
            <filename>favicon.ico</filename>
            <filename>component.php</filename>
            <folder>images</folder>
            <folder>css</folder>
            <folder>ringsend-images</folder>
            <folder>html</folder>
      </files>
      <positions>
            <position>start-blankpage</position>
            <position>footer-contractor</position>
      </positions>
