Javascript Not Showing On Custom Post Page

[mammothca]

Hello,

On one my my real estate websites, a just received a javascript code from my IDX developer to insert listings into my blog.

I am running the backcountry theme with types/views custom post types.

I inserted the script, and it appears in the source code, however it isn't producing the results.

<h3>Conestoga Condos For Sale</h3>
<script type="text/javascript" src="http://www.remax-mammoth.com/shared/global/sicm/widgets/listing-gallery.js?searchid=1425466&amp;widget=3|1|8d0808| ffffff|d90c0c|ffffff|1|cccccc|e0e0e0|0"></script><div id="sist-listings-container"></div>

The URL is http://www.mammothrealestateblog.com...kes-california

Do I need to add any code to functions.php or the the script section under genesis themes?

Any help would be appreciated.

Thanks
Doug
