Var not recognised by php?

Question

Why isn't the "finco" not recognised/passed to php? I'm not getting the text results!!
CODE:
var finco = "motors01";
XMLParser.load("www.abc.com/myfile.php"+finco, onFinish);
function onFinish($success:Boolean, $results:Object, $xml:XML):Void {
  if ($success) {
  category.text += $results.category[0].value;
  namez.text += $results.namez[0].value;
PHP
$query = 'SELECT * FROM abstart';
$results = mysql_query($query);
$SomeVar = $_GET['finco'];
$query = "SELECT * FROM abstart WHERE idcode = '$SomeVar'";
$imagepath = "";
$results = mysql_query($query);
if($line = mysql_fetch_assoc($results)){
header("Content-type: text/xml");
echo '<?xml version="1.0" encoding="utf-8"?>';
echo "<item>";

Thank you!
When I tried to add the rest the result was like this. Why is that? Which area should be altered to avoid this?
result1 = Displayed allright
result2 = Displayed allright
CN1.text=CN1s data + CN2s data + CN3s data + etc...
CN2.text=undefined
CN3.text=undefined
CN4.text=undefined
CN5.text=undefined
CN6.text=undefined
CN7.text=undefined
The Code:
result1.text="";
result2.text="";
CN1.text="";
CN2.text="";
CN3.text="";
CN4.text="";
CN5.text="";
CN6.text="";
CN7.text="";
image_mc.loadMovie();
var senderLoad:LoadVars = new LoadVars();
var receiveLoad:LoadVars = new LoadVars();
receiveLoad.onData = function(src) {
  var a:Array=src.split(",,");
  result1.text=a[0];
  result2.text=a[1];
  CN1.text=a[2];
  CN2.text=a[3];
  CN3.text=a[4];
  CN4.text=a[5];
  CN5.text=a[6];
  CN6.text=a[7];
  CN7.text=a[8];
  image_mc.loadMovie(a[9]);
