Mails been down since this morning (sorry, that's yesterday morning). Anyway, not sure if this went through, so here it is again. ------ The bottom line is I want to allow everything in the expression and nothing else. The new line does not seem to be an issue - I can put as many returns as I want, but as soon as I add some punctuation, it falls apart. As I said before, the ! and the period from my original example are reported as invalid - as they are in the expression they should be valid, I'm sure there are other examples as well, but you can see what the problem is. If I take out the ! and period from my example and leave the new lines in, it works fine.
