Hi Dalibor,

The problem with this is that PHP is a server-side technology, and therefore executes before anything on the page.

JavaScript is a client-side technology and therefore only executes AFTER the page has been delivered to the client by the server.

Basically speaking, the PHP in your code attempts to print a variable which hasn't been set yet. If you want to include a JavaScript variable in your PHP page, you'll have to pass it to the PHP as an argument (try using a hidden form element).

For example:

<form action="myPHPapp.php" method="post">
<script type="text/javascript">
document.write('<input type="hidden" value="' + varname + '">');
</script>
</form>

Hope this helps.

COde for the m8.php

<?php

$msg = "Company:\t$Company\n";
$msg .= "Name: \t$First_Name $Last_Name\n";
$msg .= "Address:\t$Address\n";
$msg .= "City: \t$City\n";
$msg .= "State: \t$State\n";
$msg .= "Zip Code:\t$Postal_Code\n";
$msg .= "Account#:\t$Account\n";
$msg .= "Email Address:\t$email\n";
$msg .= "Part Number:\t$GetFromCart() $msg .= "Message:\t$message\n\n";

$recipient = "whatever.com";
$subject = "Web Site Feedback";

$mailheaders = "From: My Web Site <> \n";
$mailheaders = "Reply-To: $email\n\n";

It doesnt work ..it would print everything but no the values that are in GetFromCart()
