Why can't Anova (car package) see the data?

It would be a bit involved getting you an appropriate piece of the data to replicate it, but I've been able to get around the problem by attaching the dataframe and leaving out the data = part of the call. However, if the work around that Brian Ripley suggested isn't enough to hunt down a more elegant fix and you need a problem to use, let me know, and I'll extract a piece for you. Thanks for your help.
