Steve,
It should be as simple as taking the decision tree ruleset that you ended up with and coding that on your web page. EM should even give you the resulting scoring code in PMML that you could load directly to your webpage...theoretically that is. I've not specifically done that in practice with this package, but other similar packages have similar functionality. If it's that simple, you could always code up the ruleset by hand.
So, for your example, when a potential customer visits your page, by asking them the questions that were on your tree, and in that order, you should be able to place them into the appropriate product page. So, I'm a female visiting your page....since AGE seems to be the primary differentiator, ask that question first. Let's say I'm 40, then you would pop up the jewelery page.
Does that make sense?
