Embed javascript into banner

 I am trying to embed a Jira issue collector into our WC pages to collect tickets from users.  Jira created the issue collector and gave me the javascripts to embed.  I have tried to embed a variety of ways, but I cannot seem to get it to display or work correctly.  I've tried a couple ways shown below with no real success.  Both appear to load initally, then the button they are supposed to create disappears.  My console does not show errors, it just appears like the clickable button gets hidden or moved back in the page.  

I am just adding these into my banner.txt file.  I have the begin_custom.jspf modified to include the message banner.  Generally the message banner works okay.  Any pointers what I am doing wrong?  I'm not an html person. 

<script type="text/javascript" src="<Jira_page>/com.atlassian.jira.collector.plugin.jira-issue-collector-plugin:issuecollector.js?locale=en-US&collectorId=cac99114"></script>

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>jQuery.noConflict();</script>
// Requires jQuery!
jQuery.ajax({
 url: "<Jira_page>/download/batch/com.atlassian.jira.collector.plugin.jira-issue-collector-plugin:issuecollector-embededjs/com.atlassian.jira.collector.plugin.jira-issue-collector-plugin:issuecollector-embededjs.js?locale=en-US&collectorId=cac99114",
 type: "get",
 cache: true,
 dataType: "script"
});
