In place editor value of text box

When using the in place editor, it creates a form with a text field
having the name “value”. In my in place editor tag, I want to use the
value of that text field as one of the parameters passed to my action.
I’m trying to use form.value.value but that doesn’t work (it doesn’t
recognize form.value.value)

      <%= in_place_editor 'add_country_area',
      :url => {:action => 'add_country_area' },
      :with => 

“‘descr=’+form.value.value+’&country=’+document.add_trip.country.selectedIndex”
%>

How do I access this value in my controller? If I try to just grab
params[:value] it doesn’t recognize that either.

Thanks
