hey all,
I have either given up or taken a break, not sure with on table / relationship structure with considerable help from both gemma-the-husky and Mihail.
Thank you both as much for your patience as technical help.
I'm jumping to the forms development and going to try what I need via queries and SQL.
I'm trying to do a series of cascading combo boxes which have worked out fine, right till I hit the first junction table.
I will include the VBA code below as well as a screenshot but here's how it goes.
REGION cascades down to COUNTRY cascades down to PORT and then to CARRIER.
This is for a shipping program.
When it gets to PORT and are trying to cascade to the various CARRIER's thats where it hits a junction table of PORT_CARRIER.
Hopefully the screen shot will better explain it.
Here is REGION to COUNTRY:
Me.cboCountry.RowSource = "SELECT COUNTRY.CNTRY_ID, COUNTRY.COUNTRY FROM COUNTRY " & _ " WHERE REG_ID = " & Nz(Me.cboRegion) & _
" ORDER BY COUNTRY"
Me.cboCountry = Null
COUNTRY to PORT :
Me.cboPort.RowSource = "SELECT PORT.PORT_ID, PORT.PORT FROM PORT " & _
" WHERE CNTRY_ID = " & Nz(Me.cboCountry) & _
" ORDER BY PORT"
Me.cboPort = Null
PORT to CARRIER:
Me.cboCarrier.RowSource = "SELECT PORT_CARR.PORT_ID, PORT_CARR.CARR_ID FROM PORT_CARR " &_ " WHERE PORT_ID = " & Nz(Me.cboPort) & _
" ORDER BY CARR_ID"
Me.cboCarrier = Null
PORT to CARRIER is where the problem is.
It populates the combo box, but with the ID numbers instead of actual CARRIER names.
(the Junction table are two PK fields and are lookups to PORT in PORT table and CARRIER in CARRIER table.)
Is there a magic spell for cascading combo boxes when you hit a junction table?
