Passing data to a PHP script

[Sebarry]

Hi,

I have the following actionscript that invokes a PHP script.

var articlesToRetrieve = 5;
var currentIndex = 0;

varSenderTitles = new LoadVars();
varReceiverTitles = new LoadVars();

var limit = currentIndex + "," + articlesToRetrieve;
var url = "http://www.bemod.co.uk/scripts/GetNewsArticles.php?limit=" + limit;

//Send request.
varSenderTitles.sendAndLoad(url, varReceiverTitles, "GET");

//Retrieve the thread text.
varReceiverTitles.onLoad = function() 
{
     .....
}

The PHP script is:

$sql = "SELECT news_id, title FROM news ORDER BY title DESC LIMIT " . $_GET['limit'];

$result = $con->sqlExecute($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
     $articles .= $row['news_id'] . '~' . $row['title'] . '|';
}

$articles = urlencode($articles);

The PHP script works fine when I replace $_GET['limit'] with a hardcoded value. When I print out what is returned into varReceiverTitl es it is undefined.

Any ideas?
