Cascading Combo Boxes -- Part 1

[rich]

I need some help w/ cascading combo boxes in conjunction with subforms.

I posted a similar thread before, but I still haven't been able to get this
to work.
(Ken Snell was so kind to get me up to speed until this point and I'm not
sure if
I truly understood his additional recommendations in respect to using
subforms).

Before I post my question, I'd like to provide some detailed information
about the tables, forms, subforms, etc. The description is quite lengthy,
so please bare w/ me.


I have a 3-tier One-To-Many table structure.
- Division is "parent" of SectionCode
- SectionCode is "parent" of BilletCode


TABLE (and relationships):
**************************

tblDivisions
============
DivisionID (Autonumber)
Division (Text)

tblSections
===========
SectionID (Autonumber)
DivisionIDfk (Number)
SectionCode (Text)

tblBilletCodes
==============
BilletCodeID (Autonumber)
SectionIDfk (Number)
BilletCode (Text)



FORMS AND SUBFORMS:
*******************

First,
1. I have a mainform (frmBoards). This form contains general board
information. Then,
2. tblDivisions is stored on frmDivisions
3. tblSections is stored on frmSections
4. tblBilletCodes is stored on frmBillets

then
A. frmDivisions has a subform (frmSections)
B. frmSections has a subform (frmBillets)


NOTE: all 3 forms (frmDivisions, frmSections, frmBillets) are displayed in
"Datasheet"
view



DATA DEPENDENCIES FOR THE COMBO BOXES
*************************************

At this time (for testing purposes), I have the 3 combo boxes for Division,
SectionCode, and BilletCode on a single form.

The cascading dependencies for Divisions, Sections, and Billetcodes are
better understood with the following geographical example:

Let's say:
- Division = State
- SectionCode = City
- BilletCode = Community

For instance, the values in the combo must are dynamic based on their parent
value(s):
- If State "CA"
- then City "San Francisco" or "Los Angeles"
- then Community "SF North", "SF South", "LA North", "LA South"

- If State "FL"
- then City "Miami" or "Jacksonville"
- then Community "MIA North", "MIA South", "JVL North", "JVL South"

etc.... the same principle applies for my 3-tier relationship betwen
Division,
SectionCodes, and BilletCodes
