Hi Charlie, It turned out that the "delete_nested_hash_value" error was a bug - it should actually have been trying to call the method named "delete_nested_hash_value". However, that still wouldn't have fixed things for you, because the Label element was deliberately deleting the submitted value, as a security precaution, because the Label element doesn't want someone submitting values for what's not really a form field. So I've now added a check - and if there's another field on the form with the same name as the Label element, the submitted value won't be deleted - so it should now work for you using a Hidden field with the same name as the Label element. The fix is in svn, and will be included in the next cpan release.
