sending data from flash? - help, error in my code?

hi all,

ok I'm trying to send data from a flash app to the server using the following code:

Code:

function sendXML(){
    _root.cities["tempContainer"].attachMovie("pointer","point_" + i,_root.cities["tempContainer"].getNextHighestDepth(),{pointX:_root.cities["tempContainer"]["point_Changeable"].point._x,pointY:_root.cities["tempContainer"]["point_Changeable"].point._y,textX:_root.cities["tempContainer"]["point_Changeable"].pointBack._x,textY:_root.cities["tempContainer"]["point_Changeable"].pointBack._y,cityText:_root.cities["tempContainer"]["point_Changeable"].pointBack.cityName.text,color:_root.cities["tempContainer"]["point_Changeable"].color,fontSize:_root.cities["tempContainer"]["point_Changeable"].fontSize,urlGo:_root.cities["tempContainer"]["point_Changeable"].urlGo});
    
    var xmlText:XML = new XML();
    var xmlString:String = "<country id = " +selectedCountryNum+ "><point>"+"<dotx>"+_root.cities["tempContainer"]["point_Changeable"].point._x+"</dotx>"+"<doty>"+_root.cities["tempContainer"]["point_Changeable"].point._y+"</doty>"+"<labelx>"+_root.cities["tempContainer"]["point_Changeable"]._x+"</labelx>"+"<labely>"+_root.cities["tempContainer"]["point_Changeable"]._y+"</labely>"+"<city>"+_root.cities["tempContainer"]["point_Changeable"].pointBack.cityName.text+"</city>"+"<url>"+_root.cities["tempContainer"]["point_Changeable"].urlGo+"</url>"+"<fontsize>"+_root.cities["tempContainer"]["point_Changeable"].fontSize+"</fontsize>"+"<fontcolor>"+_root.cities["tempContainer"]["point_Changeable"].color+"</fontcolor></point></country>";
    xmlText.parseXML(xmlString);
    
    _root.cities["tempContainer"]["point_Changeable"].removeMovieClip();
    
    //------------------------------
    //--- SEND XML TO SERVER -------
    //-----------------------------

    xmlText.send("parsexml.php","_self");
}

Code (markup):

The parsexml.php file is called without any problems however there's not data sent to the file at all. Is there an error in the code above?

thanks a lot for the help, I'm really lost here and don't seem to get an answer anywhere
