Problem with multiple insert

I have done this before without any problem. However I have spent a whole day trying to get this to work and it just wont.

I am trying to do a very simple multiple upload. I have a table with 3 fields ID, resortID and text.

On my page 'ID' is automatically generated and, the text field called 'text' is repeated 20 times and 'resortID' is static and should get the value from the url <?php echo $_GET['resortID']; ?>

The value of 'text' insert correctly however there is no value in the 'resortID' field. I display the results of <?php echo $_GET['resortID']; ?> on the page so I know it is generated (and it's in the url)

I have attached a copy of the page

the resortID querysting is present when the page loads, but it is not included as a part of the forms action, so when the form posts, it is no longer present

change:

<form  action="resortunitamenities_Insert.php" method="post" name="WADAInsertForm" id="WADAInsertForm">

to:

<form  action="resortunitamenities_Insert.php?resortID=<?php echo(isset($_GET['resortID'])?$_GET['resortID']:""); ?>" method="post" name="WADAInsertForm" id="WADAInsertForm">
