Adv. Rails Recipes - Problem w/ DRY forms

Hello.

I'm following the example in the Advanced Rails Recipes book for Keeping
Forms DRY and Flexible - #22.

I think the last little hurdle that I have is applying my CSS style to
the field labels.

This is in the partial for displaying the field

<p>
  <span class="field_label">
    <%= label %>
  </span>
  <span class="form_field">
    <%= element %>
  </span>
</p>

I want to stylize the class field_label.

When I view the html, it looks like this:
<span class="field_label">
    <label for="order_customer_id">Customer</label>
</span>

My thought is that the label for breaks the CSS style.

The code that generates the html is this:
:label => label(field, options[:label])

Any ideas on how I can apply my CSS style?

Thanks!

Nevermind... I found the problem. It wasn't recognizing my stylesheet.
