Widget not filtering by forum

I am using the following snippet on my page. This loads my forum widget which I have styled and setup how I like. However, I notice that it is not filtering by forum category, despite specifying one. It should be returning articles from http://support.exclaimer.com/list/36966-forum/?category=14939 

var _ues = {  host:'support.exclaimer.com',  forum:'36966',  category:14939,  lang:'en',  tab_show:false,  container_id:'ue-embedded-widget',  };    (function() {  var _ue = document.createElement('script'); _ue.type = 'text/javascript'; _ue.async = true;  _ue.src = ('https:' == document.location.protocol ? 'https://'">https://' : 'http://') + 'cdn.userecho.com/js/widget-1.4.gz.js';">https://' : 'http://') + 'cdn.userecho.com/js/widget-1.4.gz.js';</a>  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(_ue, s);  })();

Result:
