I have been right through all the instrcutions on this thread and still stumped. I am trying to add a field to allow customer to enter thier website address.
When I get to

9. Now open file: includes/templates/YOURTEMPLATE/templates/tpl_modules_create_account.php

9a. Now search for the following code:

<?php
if (ACCOUNT_FAX_NUMBER == 'true') {
?>
<br class="clearBoth" />
<label class="inputLabel" for="fax"><?php echo ENTRY_FAX_NUMBER; ?></label>
<?php echo zen_draw_input_field('fax', $account->fields['customers_fax'], 'id="fax"') . (zen_not_null(ENTRY_FAX_NUMBER_TEXT) ? '<span class="alert">' . ENTRY_FAX_NUMBER_TEXT . '</span>': ''); ?>
<?php
}
?>

I open the file and find the above section but it is slightly different to what I have. This is not in my file
$account->fields['customers_fax'],

So I tried entering

<br class="clearBoth" />
<label class="inputLabel" for="website"><?php echo ENTRY_WEBSITE_NUMBER; ?></label>
<?php echo zen_draw_input_field('website', ' ','id="website"') . (zen_not_null(ENTRY_WESITE_NUMBER_TEXT) ? '<span class="alert">' . ENTRY_WEBSITE_NUMBER_TEXT . '</span>': ''); ?>
<?php
}
?>

And if I make the changes as suggested then view the page /index.php?main_page=login The ID and Password fields are still there , but everything else has gone.

help, please
