In this case, I can take advantage of the bad HTML design with this:
><dtml-if check_box>
Checked!
</dtml-if>

> You want something like:
> <dtml-if expr="REQUEST.has_key('check_box') and check_box == 'on'">
>   Checked!
> </dtml-if>

I'm guessing I can use this in other situations. 

Thanks so much!
