add body id param to nested template - DW8

did it once, can't get it, please help!

Hi
I'm working on a site where the nav changes depending on the section you're in, using body id tags. To change this I usually use

<!-- InstanceParam name="id" type="text" value="tab" passthrough="true" -->

in the head, which makes the body id editable as a "modify template properties" function.

I took this out after I'd built the site because the navigation wouldn't allow it, but I've since added a nav system and I CAN'T GET IT BACK IN! I've been working on the site for 12 hours, so I'm hoping this is something simple I'm missing.

DW 8 won't let me add it to the master or any nested templates. Urgh.
