Custom Aweber Form

I'm no expert, but since nobody else has replied here's my 2 cents

Is the form file in a .html or .php ?

For php you could try something like this:

<input type="hidden" name="meta_message" value="<?  $_POST['custom Current Week'] ?>" />

PHP:

For a .html file, yeah I think you need javascript something like this:

<script>
  function CopyValue(obj1, obj2)
  {
     var visibleField = obj1;
     obj2.value = visibleField.value;
  }
</script>

</head>


<form method="post" class="af-form-wrapper" action="http://www.aweber.com/scripts/addlead.pl"  onSubmit="CopyValue(custom Current Week, meta_message)">
<input type="hidden" name="meta_web_form_id" value="1757948816" />
<input type="hidden" name="meta_message" value="" />

Code (markup):

It should copy the value of "custom Current Week" and put it into the value of "meta_message", have a mess-around with those two ideas they may need tweaking. Like the javascript might need id's to work with so add an id to meta_message id="meta_message" and change the onSubmit to onSubmit="CopyValue(awf_field-6973267, meta_message)"
