cfselect bind to another cfselect

Hi all, need help with a cfselect bind.

I'm using this as a tutorial: http://tutorial544.easycfm.com/

Here's my page:  http://pcgrecords.com/vol/test.cfm

The first select, year, isn't bound, so ignore that.  But the rest of the cfselects on that page have a bind to the one before it.  (So the 'makes' one populates the 'models', and etc.)

Everything is ok until I get to the last one.  What I really want, is for the last cfselect, Select an OE, to be bound not just to the engine cfselect before it, but to the select model field as well.

Please help!

Here's the relevant code on the page, and the cfc is attached in a txt file.

   <tr>
         <td>Select Model:</td>
         <td><cfselect name="model" bindOnLoad="Yes" bind="cfc:data.getmodel({makes})" />
         </td>
</tr>
 <tr>
         <td>Select Engine:</td>
         <td><cfselect name="engine" bindOnLoad="Yes" bind="cfc:data.getengine({model})" />
         </td>
</tr>
<tr>
         <td>Select OE:</td>
         <td><cfselect name="OE"  bind="cfc:data.getOE({engine})" />
         </td>
</tr>
