Actually, that did help. Didn't realize you meant to repalce all the section with sect1s in the whole document - after I did that, the error goes away.
I guess it just wants me to be consistent - use section through the document, or use sect1, but be consistent (before I was using section unless I needed to nest a subsection)?
Hey, its a machine :-) It does what you say, not what you want :-) Yes, consistent is good. regards DaveP
