Thanks, all you guys, for all the help you gave me last week. The story was that I was recommended by a friend for a job using FrameMaker. I pointed out that although the content is my niche (APIs), I have never professionally used FrameMaker (apart from a couple of home courses I did a while back). My friend said not to worry since the books are all already set up, I only need to update some things, and the client does not do any fancy stuff.
Well ... when I got there, I found a completely different story: not one of the five or so FrameMaker books I had to update actually "compiled" properly. Every one had one or more critical PDF generation errors, that I hadn't the fogginess how to solve. Anyway, I worked hard, slept on the floor, and -- most importantly -- you guys helped me out on the basic stuff. The client was delighted with the result, and assumes that I am an FM expert. Great thanks to you all! - avi
