Is it the formresults.php page that displays blank?
I see a problme with the following code on that page:
<?php session_start();
$_SESSION[customeremail]="$_POST[customeremail]";
$_SESSION[customeraddress]="$_POST[customeraddress]";
$_SESSION[NWDallas]="$_POST[NWDallas]";
$_SESSION[NDallas]="$_POST[NDallas]";
$_SESSION[SDallas]="$_POST[SDallas]";
$_SESSION[Income]="$_POST[Income]";
$_SESSION[Age]="$_POST[Age]";
$_SESSION[Listmenustate]="$_POST[Listmenustate]";
?>
it should be:
<?php session_start();
$_SESSION['customeremail']=$_POST['customeremail'];
$_SESSION['customeraddress']=$_POST['customeraddress'];
$_SESSION['NWDallas']=$_POST['NWDallas'];
$_SESSION['NDallas']=$_POST['NDallas']
$_SESSION['SDallas']=$_POST['SDallas'];
$_SESSION['Income']=$_POST['Income'];
$_SESSION['Age']=$_POST['Age'];
$_SESSION['Listmenustate']=$_POST['Listmenustate'];
?>
iof your still having problems, try adding the following at line 1 of the page that is showing blank to turn error reporting:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
if Dreamweaver is showing errors about permissions on the server, try deleting the webassist directory from the server, then uploading it again.
