how to edit the code for the subscription form

i am trying to edit this code to make the table longer and i don’t know where it is.
<script type=”text/javascript”>
//<![CDATA[
if (typeof newsletter_check !== "function") {
window.newsletter_check = function (f) {
var re = /^([a-zA-Z0-9_\.\-\+])+\@(([a-zA-Z0-9\-]{1,})+\.)+([a-zA-Z0-9]{2,})+$/;
if (!re.test(f.elements["ne"].value)) {
alert(“The email is not correct”);
return false;
}
if (f.elements["ny"] && !f.elements["ny"].checked) {
alert(“You must accept the privacy statement”);
return false;
}
return true;
}
}
//]]>
</script>

<div class=”newsletter newsletter-subscription”>
<form method=”post” action=”http://www.kingadowproductions.com/wp-content/plugins/newsletter/do/subscribe.php” onsubmit=”return newsletter_check(this)”>

<table cellspacing=”0″ cellpadding=”3″ border=”0″>
