Cascading Combo Boxes -- Part 2
THREAD IS CONTINUED FROM POST "CASCADING COMBO BOXES - PART 1"
================================================== ============ CURRENT COMBO BOXES (SINGLE FORM) ********************************* Here's how the cascading combos work on a SINGLE form (which I need to translate into the mentioned forms and subforms).

Alright, at this time, my question is straightforward... how do I modify this row sources & On Change event handlers to get the same results using multiple subforms? Thanks so much in advance, Tom |

Cascading Combo Boxes -- Part 2
rich,
Am I to guess that you want all three subforms on one form and if you change the record pointer on any of the "parent" forms that the system should automatically update the child forms? It can be done but not without some coding. My question is what is wrong with the combo boxes that you have already created and tested? Dan "rich" wrote in message ...

Cascading Combo Boxes -- Part 2
Dan, thanks for the prompt reply.
Here's the relationship of the forms/subforms. 1. Mainform.... which has 2. Subform "frmDivision" which has 3. Subform "frmSections" which has 4. Subform "frmBillets" Again, the successfully tested 3 combo boxes work currently on a single dummy form (for testing purposes). However, the above structure (1 to 4) is what I need to achieve. Hmh, I did include some coding in the post(s). Please make sure to review both posts ("Cascading Combo Boxes -- Part 1" & "Cascading Combo Boxes -- Part 2"). Altogether, this was a very lengthy thread so I had to cut into two parts.
