One problem here is that there -is- no use made of a template named
r-adv-type, so backward chaining is not done. Looking at your code
this ought to be just "adv-type", not "r-adv-type". Maybe you thought
that do-backward-chaining names a rule; it doesn't, it names a
template for which backward chaining triggers should be generated.
You've got three templates names adv-type, adv-type-ask, and adv-attr,
and rules with names like r-adv-type and
adv-type-ask-something-else. As in all types of programming, using
good names makes it easier to write and understand code, while using
bad names like these (bad in the sense that they're cryptic and all
very similar) makes it difficult. I would consider changing all the
names to "type", "attribute", "advice", "ask-advice", or whatever --
names which won't be so confusing.
Jason's also pointed out another problem, that ?x isn't defined at the
time that you use it in an assert.
