Problem with contact form

Question

Hi-
I found a contact form for my Flash website but it's not working properly. It uses ActionScript 3 and PHP, both of which I don't know much about. Because of this, I can't pinpoint the problem or how to fix it. Here's what's going on:
1) Each field in the form only allows 3 characters and no special characters such as @ _ ! . , etc...
2) When the user goes to the next field in the form, the previous field appears blank but the when clicking on that again, the original text appears.
3) When submitting the form, it just keeps saying "in progress" and never shows the confirmation text nor does the email get sent. There is an HTML file included with this form but I am not sure if I need to put that in as I have embedded this form into an SWF file so I don't think I need that code but please let me know if I am wrong about this.
I am posting both the AS code and PHP code below.. if someone can help me figure this out I would greatly appreciate it. I am not sure which file the problem is in. If someone here doesn't know PHP then at least see the AS code and let me know if the problem is in that or not. That way I can pinpoint which file the problem is coming from and then seek further help if needed. To see the form in action, go here: http://www.poojasdesigns.com/ and click on "Contact Me".. here are the codes:
ActionScript 3.0
//presistant reference to this movie's mail timeline:
var mainTL:MovieClip = this;
//start off with submit button dimmed
submit_mc._alpha = 40;
//create the LoadVars objects which will be used later
//one to send the data...
var dataSender:LoadVars = new LoadVars();
//and one to recieve what comes back
var dataReceiver:LoadVars = new LoadVars();
create listener for Key Object
this is just a U.I. thing - "wakes up" the submit button
when all fields have at least some content
var formCheck:Object = new Object();
formCheck.onKeyUp = function() {
     if (name_txt.text != '' &&
               email_txt.text != '' &&
               subject_txt.text != '' &&
               message_txt.text != '') {
          //clear any alert messages
          alert_txt.text = '';
          //enable the submit button
          submit_mc._alpha = 100;
     } else {
          //remain disabled until all fields have content
          submit_mc._alpha = 40;
Key.addListener(formCheck);
/*#######SET STYLES FOR TEXT FIELDS#######*/
//define styles for both normal and focussed
//set hex values here that work with your site's colors
var normal_border:Number = 0x000000;
var focus_border:Number = 0xFA8D00;
var normal_background:Number = 0xFFFFFF;
var focus_background:Number = 0xE9E3E3;
var normal_color:Number = 0xFFFFFF;
var focus_color:Number = 0x000000;
//create an array containing the fields we wish to have styles applied to
inputs=[name_txt,email_txt,subject_txt,message_txt];
a "for in" loop now iterates through each element in the "inputs" array
and applies our "normal" formatting to each input text field
for( var elem in inputs) {
     inputs[elem].border = true;
     inputs[elem].borderColor = normal_border;
     inputs[elem].background = true;
     inputs[elem].backgroundColor = normal_background;
     inputs[elem].textColor = normal_color;
     /*this takes care of applying the "normal" style to each of the four input fields;
          the following TextField prototypes handle highlighting when an input field
          gains focus and resetting to normal when a field loses focus*/
     inputs[elem].onSetFocus = function() {
          this.borderColor = focus_border;
          this.backgroundColor = focus_background;
          this.textColor = focus_color;
     inputs[elem].onKillFocus = function() {
          this.borderColor = normal_border;
          this.backgroundColor = normal_background;
          this.textColor = normal_color;
//finally: make the first field (name_txt) selected when the movie loads
Selection.setFocus(name_txt);
/*DEFINE SUBMIT BUTTON BEHAVIOR*/
submit_mc.onRelease = function() {
     //final check to make sure fields are completed
     if (name_txt.text != '' &&
               email_txt.text != '' &&
               subject_txt.text != '' &&
               message_txt.text != '') {
          alert_txt.text='';//clear any previous error messages or warnings
          //advance playhead to frame 2 - the "processing" message
          mainTL.play();
          //assign properties to LoadVars object created previously
          dataSender.name = name_txt.text;
          dataSender.email = email_txt.text;
          dataSender.subject = subject_txt.text;
          dataSender.message = message_txt.text;
          //callback function - how to handle what comes abck
          dataReceiver.onLoad = function() {
               if (this.response == "invalid") {
                    mainTL.gotoAndStop(1);
                    alert_txt.text = "Please verify your email address - it appears to be incorrect."
               } else if (this.response == "passed") {
                    mainTL.gotoAndStop(4);
          //now send data to script
          NOTE: the line below presumes the Flash swf file and php script are in the
          SAME DIRECTORY on your server. If this is not the case (if for example you
          wish to put the php script along with other similar items in a "scripts"
          directory) you MUST MODIFY THE PATH. Otherwise the Flash movie won't be
          able to locate the php script.
          dataSender.sendAndLoad("processEmail.php", dataReceiver, "POST");
     } else {
          //warning if they try to submit before completing
          alert_txt.text = "Please fill out all the fields before submitting the form.";

You say you don't know much about AS3, and that you have embedded this form into an swf.  In what manner did you embed it, and what version of AS does the swf use?  Have you tried using the form in the page that was provided as a standalone test to see if it works?
