I have a breadcrumb javascript file saved in the directory with all of the webpages that are on my site. It is called "crumbs.js"

I want this script added to the template header so that it will run on all pages of my site.

I created a HTML box at the bottom of my template header and have inserted the following code to try and have the script appear:

<script type='text/javascript' src='crumbs.js'></script>

<script type='text/javascript'> <!-- doCrumbs(); //--> </script>

When I preview my site the script does not run and nothing appears at the bottom of my template header.

Can anybody help with this?
