I am looking for an example of Dynamically making a query according to critieria choosen in sever select boxs.  If a box has not selections, it is skipped.  The trick here is that I need the combo boxs to requery when ever something is selected.  If Select1 is "Bob", then Select Two has all of Bob's Jobs loaded for selection.  If Select1 is not selected then All Jobs are loaded unless Select3 with more critieria is selected.  

Anyone?

The following is a sample of the code from a custom tag I used to do what you want to do, but it is for searching for hotels. The first selection box is for country, then state, then city, then hotel. It is not tailored to your exact needs but I think you can get the concept from it. Note that In my actual code I get the neccessary records from the database before the sample code that I gave you.

khagen,

The dynamic selectbox is written in totally in javascript, nothing about query from database. But this is useful when you have those confirm and static element in the select box, else you have to play with some javascript and cfm which you must have frame to play the trick.

Let me know if you are interested on it or not. Then i can mail you some samples, currently i don't have any website for you to see becaz it's a project for my client.

If you mean populating a select box with a cf query
that is run from a value chosen in an earlier select
box, then that is possible.

Ie :-

select one has list of workers from DB - using cfquery

when a value is chosen in this box the second box
populates with jobs for the person we chose. -again using a
cfquery


Is that the idea?
