Contact Form (php) - how to prevent new window...

Question

My contact form works just fine, however, I currently have
the target set to "_blank" which is not what I want.
Rather than opening the .php file open in a new window, I
just want to go to a new frame (labeled "success" or "error")
within my flash file (which currently works fine)
So, my question is how do I send the form information to my
php file WITHOUT having to open a new window outside of my flash
file since I'm sending the user to new frame instead.
FYI: I've already tried removing "_blank" but it still opens
the php file in a new browser window.
My code below:
on (release){
var my_lv:LoadVars = new LoadVars();
my_lv.fullName = fullName_txt.text;
my_lv.email = email_txt.text;
my_lv.emailMessage = emailMessage_txt.text;
if(fullName_txt.text != "" && email_txt.text != ""
&& emailMessage_txt.text != "") {
my_lv.send("contact.php","_blank","POST");
gotoAndStop("success");
else {
gotoAndStop("error");
Any help is greatly appreciated.

Thanks for your help, Zupko.
I tried your suggestion but I'm still experiencing the same
problem. A new window still opens. Perhaps I'm doing something
wrong?
My code with your suggestion below:
on (release){
var my_lv:LoadVars = new LoadVars();
my_lv.fullName = fullName_txt.text;
my_lv.email = email_txt.text;
my_lv.emailMessage = emailMessage_txt.text;
if(fullName_txt.text != "" && email_txt.text != ""
&& emailMessage_txt.text != "") {
loadVariables("contact.php","POST");
gotoAndStop("success");
else {
gotoAndStop("error");
Your help is very much appreciated!
