highScore_lv.viewtype = “HTML”;
highScore_lv.winname = pName;
highScore_lv.winscore = score;
highScore_lv.onData = function(src:String) {
if (src == undefined) {
content_txt.text = “Error loading content.”;
return;
}
content_txt.text = highScore_lv;
};
function setSubmit() {

highScore_lv.winscore = inScore.text;
trace(highScore_lv);
}
function submit() {
highScore_lv.sendAndLoad(“http://127.0.0.1/scores.php”, highScore_lv, “POST”);
