<li class="fields">
<div class="field">
<label><?php echo $this->__('Annual Usage') ?></label>
<div class="input-box">
<input type='text' value="<?php echo $this->getValue('annual') ?>"
name='customer[usage]' id='customer:usage' class="input-text"/>
</div>
</div>
</li>
I want to add two more form fields and append them to the submit with Javascript. How do I tie into the form submission?
