How do I pass the variable to the SWF file?

What I'm wanting to do is pass a variable into an HTML file that uses the variable two ways:  1) it reads an XML file to display data (which it does correctly), and 2) pass the same variable on to a SWF file so that the SWF knows which FLV to pull in and display.

So, for example, let's say I want to use "textOnly.htm?pageNum=10001"

In my <head>, I have:

function getParameter(paramName){
  var url = ""+document.URL;
  if(url.indexOf("?") < 0 )
     return "";
  var qs = url.split('?')[1];

  var paramMap = qs.split('&');
  for(var i = 0; i < paramMap.length; i++)
      var nvPair = paramMap[i].split('=');
      if(nvPair[0] == paramName)
         return nvPair[1];

  return "";

var pageNum = getParameter("pageNum");

Currently, the pageNum will pull "10001" out of the example I used, and down in the body, I'm able to pull out the text that I want to display.

However, I cannot pass this same variable to a swf file.
<param name="movie" value="videoforHTML.swf?pageNum=' + getParameter('pageNum') + '"/>

I've tried
<param name="movie" value="videoforHTML.swf?pageNum=' + pageNum + '"/>
and it still doesn't work.

I've put quotes around pageNum in the ' + pageNum + ' section.

What am I doing wrong?  I know it's pulling the pageNum out of the header correctly, because I can alert(pageNum) and it works beautifully.  There's got to be a way to add it to the value.

Any ideas?
