@Carl Love there you go: 

file: http://www.filedropper.com/appuntitesina

matrix: http://www.filedropper.com/datipermaple

@Carl Love I did it, result: http://www.filedropper.com/screenshot2014-02-21162251

however, I don't really know how to use procedures. shouldn't it be working without them? why doesn't it? is it bug? if so, is it fixable?

thanks
