Earthlink CGI script and Flash

I've created a contact form in Flash and the script can't find the URL at Earthlink. I've talked to EL and they said use the EL CGI html code and incorporate in the Flash script. I tried a multitude of ways and get constant syntax errors. My code has no errors but can't find the URL. I've attached my code and Earthlink's sample code. Can someone show me where to put what?
Thanks for any and all help.

Earthlink's code:
<h1>Sample Form</h1>
<hr>
<form method="post" action=" http://www.domain.com/cgi-bin/mailto"> 
<input type="hidden" name="RECIPIENT" value="user@domain.com"> 
<input type="hidden" name="THANKURL" value=" http://www.domain.com/thankyou.html"> 
<p> 
<b>Name:</b><input type="text" name="name" size="30"><br> 
<b>Email:</b><input type="text" name="email" size="30"><p> 
<b>Comments:</b><br> 
<textarea name="comments" rows="10" cols="50"></textarea>
<p> 
<input type="submit" value="Send"> 
<input type="reset" value="Clear"> 
</form> 
<p>


My Flash Code:
stop();

send_btn.onRelease = function() {
var my_lv:LoadVars = new LoadVars();

my_lv.firstName = firstName_txt.text;
my_lv.lastName = lastName_txt.text;
my_lv.email = email_txt.text;
my_lv.phone = phone_txt.text;

if (firstName_txt.text != "" && lastName_txt.text != "" && email_txt.text != "" && comments_txt.text != "")
{
my_lv.send(" http://www.domain.us/cgi-bin/mailto:me@domain.us","_blank","POST");
gotoAndStop("success");
}
else
{
gotoAndStop("error");
}
}
