Hi guys, I started the manual process on four files in app\views\expenses. I made some benign to them and crashed. I'd appreciate any observations you might offer about that.
My first change was to reorder fields in each of them. That has gone without a hitch, so far as I can tell. My second change was to add comments as place-markers for the pair of fields I have to add to each of them. That caused one of them to fail: index.html.erb (and perhaps the others will when I invoke them.) I posted the commented and un-commented versions at http://www.pastie.org/962089.
