*puzzled* Did you mean ex:if-exists=".instructor" AND ex:if-exists=".coursenumber"? That is a lot easier, in that case: <div ex:if-exists=".instructor"> <div ex:if-exists=".coursenumber"> Then create this div </div> </div> > I am creating a container div with a header that will contain > a number of fields (also if-exists statements), but I only want the > container to exist if at least one of the fields has content. My solution did that, at the expense of creating duplicates (or more, if you had, say, ten properties, either of which should show the header) when more than one condition was fulfilled. So when I wrote <div ex:if-exists=".instructor">Then create this div</div> <div ex:if-exists=".coursenumber">Then create this div</div> I actually suggested that you would copy *all* the stuff (including other if-exists statements), possibly screenfuls of it, to all places where there is an "Then create this div" above. Very untidy and not nice to maintain when you make changes to that staple code (as you'd have to make the same modification in multiple places), but it should at least work. With the mentioned misfeatures. -- / Johan Sundström, http://ecmanaut.blogspot.com/ > If no fields have content, no container div, no header. It is of > course, the more complicated version.
