Error when I add a checkbox to registration

Hi, I need to add a checkbox to the registration form, so the customer can confirm whether they are VAT exempt or not. This is for a disability website and products are VAT exempt only if they are disabled. I have added text boxes with no problems. And yes all these fields have been added to the mysql table.

I edited customers.php tpl_modules_create_account.php and create_account.php

All the fields display correctly apart from the last checkbox which is what I added.

It appears as the checkbox then ENTRY_VATEXEMPTCONFIRMENTRY_VATEXEMPTCONFIRM_TEXT

So it does not name the field properly, it also does not update the sql db table to say whether the box was checked or not.

I think the error is here

<fieldset>

<?php echo zen_draw_checkbox_field('vatexemptconfirm', '1', $vatexemptconfirm, 'id="vat-checkbox"') . '<label class="checkboxLabel" for="vat-checkbox">' . ENTRY_VATEXEMPTCONFIRM . '</label>' . (zen_not_null(ENTRY_VATEXEMPTCONFIRM_TEXT) ? '<span class="alert">' . ENTRY_VATEXEMPTCONFIRM_TEXT . '</span>': ''); ?>
<br class="clearBoth" />

</fieldset>

on the tpl_modules_create_account.php page

Please help.

I realize that you want this done during the Account Creation, but it would be much easier to make this a required attribute during the checkout process................maybe?

I did think about that, but in the registration process I have included a legal form to say the customer is vat exempt and that is where I need the checkbox.

Then in the checkout process, I will do a database query to check to see if checkbox is checked. If so the prices without vat are shown, if not then vat is included.

All I really need help with is getting the checkbox and labels to display correctly and for the database to record whether the box was checked or not.
