Are you checking to see if the post variable is set in the code that handles
saving the form values to session variables? I can't tell if you're doing
this from the code you provided. If not, it's possible that when you are
returning to one of the earlier pages, you're attempting to again save the
form values even though the corresponding $_POST vars are empty. This would
cause visiting page 2 to essentially delete the data previously posted from
page 1.
Using your example:
// Only save if post variable present, which means
if (isset($_POST['lend_fname']))
{
$_SESSION['lend_fname']=stripslashes($_POST['lend_fname']);
}
Also, some users will likely click the back button during the process, which
brings up a funky message. You might try building one page that is
dedicated to saving all of the session variables, which then redirects to
the corresponding next page in the process.
