Preserving elements in cwn's

Is there a way to preserve the elements in a cwn? For instance, I have variables s(1), s(2), s(3), and when I use h2root, they are collapsed into a single variable ‘s’. Is there a way to prevent this from happening?

Thanks,
Brian.

I do not understand this problem.
Could you send a very short Hbook file reproducing this problem?
