Displaying correct data in textbox/control (depending on values selected in a combo box)

OK, here's the basic structure of my database

Station Tabl
Each station can have multiple parts (Station prim key unique

Part Tabl
Part # prim key unique.

Location Tabl
ach location can have multiple parts (Location prim key unique

I then have 2 joining tables and did one to many relationships to setup a many to many relationship as described above as per the help in access. This way for example, Station A1 could have many different parts as well as a certain number of those parts

The data itself works fine

The forms work fine , ie. ON my Station:browse parts form, I select the station (primary key) which automatically refreshes the list of corresponding parts and part #'s (which are in a subform). The station combo box is unbound

My only problem is, if I want to also display the corresponing station description (a field on the station table), I can't figure out a way of doing this. I know I want it to look a the value currently in the station combo box, and display the corresponding station description (Perhaps just in a textbox?

ANy ideas?

Thanks,

Try something along the following lines
1- Ensure that RowSource SQL for your comboBox selects the
station name as well as the station primary key. e.g.
SELECT station, stationName FROM Station
2- Ensure that the number of columns property for the combo
box = 2
2- Create a text box on the form.
3- Place code in the AfterUpdate event handler of the combo
Box as follows

{yourtextboxname}.Value = {yourcomboboxname}.Column(1)

You could achieve a simialr effect without the need for a text
box as follows
- Change the RowSource SQL to something like
SELECT stationName, station FROM Station
- Change the Bound Column to 2
- Ensure that the Number of Columns = 2
What you should then see is the Station Name appear in the
text box part of the comboBox and the subForm should still
show the correct parts

Hope That Helps

Hrmm, I tried the code you mentioned with Bound Column = 2 and the code for the textbox

However, after that , the subform did not work correctly (right parts did not show up)

Just for hell of it I also

verified with Bound Column =1 and the code referring to column(0), and it did update the textbox when I changed the stationname combo box

ANy ideas? It seems to me changing Bound Column =2 made my subform not show the right parts anymore

Any more help would be appreciated, thanks a bunch in advance
