adding php variables in hidden value

Hi all

I need help on one matter here. I have a php file which takes values
from the form which calls the page and displays it for confirmation. I
try to display using this:


From: <input name="start" type="hidden" value="<?php echo $startDate; ?
>" >


The reason behind this is that after confirmation this page will have
a form action that calls another page to store the hidden variables
into the database, but the above line will not display the value
$startDate, does anyone know why?

Thanks
Eugene
