Remember that ajax calls are asynchronous, so the code in your onComplete handler will only be executed when the call returns, while instead your final alert will be executed immediately after the code creating the request (which you must start by calling the send method, btw) - at this time the variable will always be uninitialized.

Edit: didn't notice you used aync: false (which is usually a bad idea btw...) - you still need to send the request though

requestData.send();

Edit(2): Also, it is best not to use the onComplete callback (it is called when the response returns, even before checking what was actually returned) - instead use the onSuccess callback, and be aware that there are many reasons that the response may fail, so you might want to define the onFailure callback as well and do something in there too.

    var retourn;    

    var requestData = new Request ({
        url: 'yoururl.php',
        async:false,
        onSuccess: function(response){
            retourn = response;
        },
        onFailure: function(xhr) {
            retourn = "failed";
        }
    });

    requestData.send();

            alert(retourn);
