Problem with PHP script

<?php
if(isset($_POST['submit'])){
$name = $_POST['name'];
$surname = $_POST['surname'];
$email = $_POST['email'];

?>
<div style=" margin-top:20%;">

<form action="https://www.2checkout.com/checkout/purchase" method="post">
<input type="hidden" name="sid" value="xxxxxx">
<input type="hidden" name="quantity" value="1">
<input type="hidden" name="product_id" value="3">
<input type="hidden" name="demo" value="Y"/>
<input type="hidden" name="fixed" value="Y"/>
<input type="hidden" name="pay_method" value="PPI"/>
<input type="hidden" name="cust_email" value="<?php echo $email?>" />
<input type="hidden" name="cust_name" value="<?php echo $name?>" />
<input type="hidden" name="cust_sirname" value="<?php echo $sirname?>" />
<input type="hidden" name="x_receipt_link_url" value='http://www.mysite.com/orderconfirmation.php'>
<input name="submit" type="image"  src="images/buy-button.jpg" value="Buy from 2CO">
</form>
</div>

<?php
} else {
?>




<form action="payment.php" method="post" name="formcheck" id="formcheck" onsubmit="return (formCheck(this) && Validate(form,email));">

<div class="tekst">*Name:</div><br>
<input name="name" type="text" class="TextField" size="35">
<br><br>
<div class="tekst">*Surname:</div><br>
<input name="surname" type="text" class="TextField" size="35">
<br><br>

<div class="tekst">*Email:</div><br>
<input name="email" type="text" class="TextField" size="35"  id="email">
<br><br>
<input type="image" src="images/send-button.jpg" name="submit" value="submit">

</form>
<br>
</div>
<?php

}
?>

PHP:

That is my script for 2CO payment. First when I open payment.php this form is showed

<form action="payment.php" method="post" name="formcheck" id="formcheck" onsubmit="return (formCheck(this) && Validate(form,email));">

<div class="tekst">*Name:</div><br>
<input name="name" type="text" class="TextField" size="35">
<br><br>
<div class="tekst">*Surname:</div><br>
<input name="surname" type="text" class="TextField" size="35">
<br><br>

<div class="tekst">*Email:</div><br>
<input name="email" type="text" class="TextField" size="35"  id="email">
<br><br>
<input type="image" src="images/send-button.jpg" name="submit" value="submit">

</form>

Code (markup):

WHen I use IE 8 and Opera I can fill that form but when I click on send form resets, instead it should open this

<div style=" margin-top:20%;">

<form action="https://www.2checkout.com/checkout/purchase" method="post">
<input type="hidden" name="sid" value="xxxxxx">
<input type="hidden" name="quantity" value="1">
<input type="hidden" name="product_id" value="3">
<input type="hidden" name="demo" value="Y"/>
<input type="hidden" name="fixed" value="Y"/>
<input type="hidden" name="pay_method" value="PPI"/>
<input type="hidden" name="cust_email" value="<?php echo $email?>" />
<input type="hidden" name="cust_name" value="<?php echo $name?>" />
<input type="hidden" name="cust_sirname" value="<?php echo $sirname?>" />
<input type="hidden" name="x_receipt_link_url" value='http://www.mysite.com/orderconfirmation.php'>
<input name="submit" type="image"  src="images/buy-button.jpg" value="Buy from 2CO">
</form>
</div>

use isset($_POST['submit_x']) or isset($_POST['submit_y']) instead of isset($_POST['submit']) and problem will be resolved
