I cann't fill in a subform

[Frits.van Leeuwen]

Hello everyone,

First I give you my situation.
This is the table-structure I've:

Table_computer
ID: autonumber
name: text
enz.

Table_software
ID: autonumber
name: text
enz.

Table _computersoftware
ID: autonumber
computer(ID from Table_computer)
software (ID from Table_software)

I've a form with tab-buttons made by my self (in color)
On this form I've a subform. This one I make invisable when I don't need.
On this subform I've fields.
Also on this subform I use a sub-subform. This shows a list of users who
used a computer.

An other sub-subform i like to use to fill-in with a pulldownmenu. I can
show al software in the pulldownmenu, But when I choos one, There is nothing
happen.

Who can tell me what's probebly the answare to my problem?

I made a mistake. It's not a pulldownmenu, but field where you can make a
choice in a list. (I do not know what the name is in English Access)
