That is the site you are looking at but that is not the list, it is a separate site that provides a forum like interface into the list. It is entirely independent of the list. If you like a forum style interface then by all means use that. Many much prefer the mailing list format however. > >> I don't know about you but I find that watching tutorials is nowhere >> near as good as working right through it oneself, doing the exercises, >> finding out how to interpret errors when one makes copying errors and >> so on, so I still suggest taking a few days out to work right through >> railstutorial.org. > > I will do that... > >> However, looking at your problem, I am not sure exactly what it is >> that you cannot do.

OK, I did not realise that you wanted to input a numeric value. The fact that it is an integer rather than, for example, a text string, is irrelevant to the form. You just need to use f.input. What you do with that in the controller, of course, is up to you. You must presumably validate the field accordingly. I am not sure I would recommend that a beginner uses simple form. It is a two edged sword. It does make some things very easy but because you have not learned the basics of using a form whenever you need to do something different you may not have the basic knowledge to handle it.
