Code works perfectly, Jean, though what it's doing is a bit of a mystery. You've been very kind to provide a solution and I don't want to take more of your time on the subject, but is there some documentation somewhere that explains that commands you've used so I can figure out what's going on for myself? Or if the explanation is simple, I'd greatly appreciate it so I can stop using before/after-line-breaking since I used to use it a lot (as Thomas has hinted at).
Try reading this, and feel free to ask again if this doesn't clarify it for you:
