SharePoint and Javascript 404 Error - Failed to Load Resource

Hi Everyone,

Thanks in advance for all the support and great input people provide on this site.  Big fan.

Question, I'm receiving 404 errors on my sharepoint site.  We have custom download/submit status buttons and they entail javascript/jquery/simplemodal objects.

   <link href="***Full path***/css/confirms.css" rel="Stylesheet" type="text/css"/>
   <link href="***Full path***/css/FN2CVRTheme.css" rel="Stylesheet" type="text/css"/>
   <link href="***Full path***/css/simplemodal.css" rel="Stylesheet" type="text/css"/>
   <script src="***Full path***/js/jquery-1.4.2.min.js"></script>
   <script src="***Full path***/js/jquery.highlight.js" type="text/javascript"></script>
   <script src="***Full path***/js/jquery.simplemodal-1.3.5.js" type="text/javascript"></script>
   
<script type="text/javascript">

$(document).ready(function()
{
$("table#MSO_ContentTable > tbody > tr:first-child > td.ms-bodyareaframe > table > tbody > tr:nth-child(2) >  td:nth-child(2)> table > tbody > tr:nth-child(2) >  td:first-child > table").width('300');
document.title="Document Name";
jQuery.noConflict();
$("#status").click(function()
{
var ccnsel = $("[id*='DropDownList_CCNs']").val();
       var src = "Web Part URL";
       $.modal('<iframe src="' +src+ '" height="800" width="700" style="border:0">');
});
});

Everything is referenced to a full url path and is available.  But I'm receiving theses errors within the debugger and my buttons are non-responsive or do not show up.  Any thoughts?
