This is in the StoreController and I believe it

Hi I''m very keen to learn RoR and have been following the Agile Web Development with Rails book (first edition). However, I''ve come across a problem which has had me stumped for days now.

Hi everybody, I''ve search a lot on google to help me with this one without success. I know that some people had the same problem as I have, but there solutions doesn''t seems to work for me.
