Error trying to create a static scaffold

I'm a beginner. I get that error "wrong number of arguments (1 for 2). Please let me know why this is so. I'm copying the comand from the Agile Devpl. book. thanks, Deepa

RubyScripts\depot>ruby script/generate scaffold product admin       exists app/models/       exists app/controllers/       exists app/helpers/       exists app/views/products       exists app/views/layouts/       exists test/functional/       exists test/unit/       exists public/stylesheets/ wrong number of arguments (1 for 2)

your book is out of date. that generator looks like ruby script/generate scaffold product name:string description:text

would create a scaffold (probably not the same one your book describes) and a migration creating the appropriate table with a name column of type string and a text column called description.
