retrieve data from SQL

I need to display data based on the column name.  The name is captured from the URL parameter and passed to Flash with Javascript.

Flash retrieve it with:

var varMedia = ExternalInterface.call("getParameter1");

Then I use the following function to retrieve and display data:

function displayRatingOnSQL():void

{

  var myTextLoader:URLLoader = new URLLoader();

  myTextLoader.dataFormat = URLLoaderDataFormat.VARIABLES;

  myTextLoader.addEventListener(Event.COMPLETE, onLoaded);

  function onLoaded(e:Event):void

  {

  var tAverage = (e.target.data.Average);

  var tTotalVotes = (e.target.data.TotalVotes);

  var tTotalRate1 = (e.target.data.star1);

  var tTotalRate2 = (e.target.data.star2);

  var tTotalRate3 = (e.target.data.star3);

  var tTotalRate4 = (e.target.data.star4);

  var tTotalRate5 = (e.target.data.star5);

  var temp = tTotalRate5 + "\n" + tTotalRate4 + "\n" + tTotalRate3 + "\n" + tTotalRate2 + "\n" + tTotalRate1;

  totalForEachStar.text = temp;

  tAve.text = tAverage;

  totalVotes.text = "(" + tTotalVotes + ")";

  }

  var extraString = Math.random();

  myTextLoader.load(new URLRequest("http://dntin1web01/tpas/SQL/GniePageRatePageRead.asp?qs="+ extraString));

}

In ASP page, I have the following to pick up name for the column to extract data:

Dim tPageMedia

tPageMedia = Request.Form("varMedia")

Then I try to use the following to retrieve:

SQL = SQL & "WHERE ( [PageName] = " & "'" & tPageMedia & "') "

I got nothing. It works if I put a hard coded name replacing the dynamic one.

How can I pass the varMedia to ASP page? The variable in Javascript is var1.
