Fred, I don't have much time today, but here is my initial assessment of what might be going wrong with your page: You display add.php which draws a form for data. You submit that form to add.php (itself). The form redraws inside the page. You get errors when add.php looks for data in the $HTTP_POST_VARS array because the page is fresh and that array is empty. Problem is that there is no code to handle the data that was entered in the first place. Once you hit submit, the add.php page is (re)drawn in its original state - with no values in the fields. Therefore, when the $_POST['varname'] statement looks in $HTTP_POST_VARS, there's nothing to display so you get the Undefined Index errors. It's almost like refreshing the page. My advice would be to separate the code for the data entry and data handling parts of your project into independent scripts. Use add.php to collect the data then send the data to a php script called handleAdd.php that gets the name/value pairs and submits them to the database. After submitting the data to the database in handleAdd.php, forward the user back to another page (add.php again, if you want) where they can get some kind of confirmation the data was entered. A further recommendation would be to provide the list with the code you gave to me so maybe somebody else with a little more free time might be able to assist you further. Sorry I couldn't provide any more help.
