I'm going to start off by saying that I am a brand new user of
cfajax. I'm working on an application that already has cfajax to
populate a single drop down list and i'm using this code. I am trying
to create a form with 3 recursive calls to the database which
populates the drop down lists.

The attached code is just my starting point. I'm trying to get the
first drop down list activate the code to populate the second drop
down list but i'm having no luck. And since i'm not receiving an
error message it's difficult to figure out why nothing is happening.

Anybody have a thought as to what i'm missing? Or know a website that
can assist me in this?

Any help is greatly appreciated. Thanks in advanced!

Jennifer
