unfilled fields in forms

[kona72]

How do I get my script to not send un-filled fields to the email?

<?php

if(isset($Submit))
{
if($name != "" && $email != "" && $sda != "")
{
$message = "Saskatchewan Dietitians Association Continuing Competency Form:<br><br>
Name: $name<br>
SDA Number: $sda<br>
Street Address: $street<br>
City: $city<br>
Email: $email<br>
Date: $date<br>
Description of Activity: $description<br>
Category: $category<br>
Hours: $hours<br>
Credits: $credits<br>
Benefit of Activity: $benefit";

$headers = "MIME-Version: 1.0\n";
$headers .= "Content-Type: text/html; charset=iso-8859-1\n";
$headers .= "X-MSMail-Priority: High\n";
$headers .= "From: <$email>\n";
$headers .= "Reply-To: <$email>\n";

mail("[e-mail]", "Continuing Competency Information from Website", $message, $headers);

header("Location: thanks.htm")
;
}
else
{
$error = "y";
}
}
?>

thats what this line is doing

if($name != "" && $email != "" && $sda != "")

its checking if the variables are empty

if you still want to send the email, but just not have it with blank entries like

Street Address:<br>

then check each individually

$message = 'blah<br>';

if ($street != '') {
    $message .= "Street Address: $street<br>\n"; // notice im using .=
}

if ($hours != '') {
    $message .= "Hours: $hours<br>\n";
}

God I hate to ask this again, but where in the code do I place this?? I have tried a few places but nothing....
