[Plugin: Shortcode Exec PHP] embedding form handlers – extra carriage returns

I am using a form handler in my php code and embedding the shortcode in a wordpress page. I am getting carriage returns entered into the page above the form – the number of carriage returns seems to correspond with the number of lines I have in the form handler. Any way to correct this?

My code:
if (isset($_POST[‘wc_firstname’]))
$wc_firstname = $_POST[‘wc_firstname’];
if (isset($_POST[‘wc_lastname’]))
$wc_lastname = $_POST[‘wc_lastname’];
if (isset($_POST[‘wc_address1’]))
$wc_address1 = $_POST[‘wc_address1’];
if (isset($_POST[‘wc_address2’]))
$wc_address2 = $_POST[‘wc_address2’];
if (isset($_POST[‘wc_city’]))
$wc_city = $_POST[‘wc_city’];
if (isset($_POST[‘wc_state’]))
$wc_state = $_POST[‘wc_state’];
if (isset($_POST[‘wc_zip’]))
$wc_zip = $_POST[‘wc_zip’];
if (isset($_POST[‘wc_email’]))
$wc_email = $_POST[‘wc_email’];
if (isset($_POST[‘wc_attendees’]))
$wc_attendees = $_POST[‘wc_attendees’];
if (isset($_POST[‘wc_email’]))
{
save_wcinfo($wc_firstname, $wc_lastname, $wc_address1, $wc_address2, $wc_city, $wc_state, $wc_zip, $wc_email, $wc_attendees);
}
?>
<form method=”post” action=””><table><tr>
