That's right. I was wondering how to reference in case automatic numbering was possible.

Yes, i alredy found your guide, but it's very hard for me to follow as i don't know a word in german :) So what i'm missing now is only the ability to replicate the result i saw on page 12 of the pdf on lyx (that is, working with aling and alignat). Next step will be learning split and multiline to deal with long formulas. It would be very kind of you if you could give me some suggestions to accomplish this diffucult (for me) task. Thank you a lot for your reply! Greetings Pelux
