How to pull URL parameters into my Captivate 6 flash

Question

I want to be able to parse a parameter being passed in the URL to my Captivate video and then use it after the file is over.   e.g. a username that is picked up by another web page.  Is there an easy way to do this.
Looking through old posts, is see using the m_MovieHandle as the area to place my flash code, but everything so far I've tried doesn't bring in the variable.   I'm kinda new to flash.
Thanks

Put this JavaScript code in a separate .js file.  I called mine utilities.js:
     /* Utility to get a URL Parameters as queryString object */
     var queryString = (function(a) {
          if (a == "") return {};
          var b = {};
          for (var i = 0; i < a.length; ++i)
               var p=a[i].split('=');
               if (p.length != 2) continue;
               b[p[0]] = decodeURIComponent(p[1].replace(/\ /g, " "));
          return b;
     })(window.location.search.substr(1).split('&'));
     /* Utility function to Set a Captivate Variable with a URL Parameter */
      var setCpVariableWithURLParameter = function(cpUserVariableName, urlParameterName){
          /* Get the requested URL Parameter from the URLParams Object */
          var variableValue = queryString[urlParameterName];
          /* Check for HTML5 vs. SWF output */
          if (typeof window.cp==='undefined') {
               /* We have SWF output, so Get the Captivate Object */
               var objCp=document.getElementById('Captivate');
               if(objCp && objCp.cpEISetValue){
                    /* Set the Captivate User variable with the JavaScript variabe, variableValue */
                    objCp.cpEISetValue('m_VarHandle.' + cpUserVariableName, variableValue);
          } else {
               /* We have HTML5 output */
               if(cp.vm && cp.vm.setVariableValue){
                  cp.vm.setVariableValue(cpUserVariableName, variableValue);
Include this .js file in the header of the <ProjectName>.htm file of the swf published output by using a script tag:
<script src="utilities.js" type="text/javascript"></script>
Where utilities.js is at the root of the published project (where the published .swf file lives).
Also add this script tag to the header of the HTML5 output index.html file. 
To use the setCpVariableWithURLParameter() function, you would make this call inside of a JavaScript action in Captivate:
setCpVariableWithURLParameter('v_Name', 'userName');
Where 'v_Name' is the Captivate user Variable you want to set and 'userName' is the name of the URL parameter.
Give that a try and let us know how it goes.
