Cascading ComboBoxes

[lee123]

Hello its been a while since i have come to this web site and its been a while since i have done any programming but here i am. my question is going to be difficult to explain but here it goes. i have been trying to make a auto parts database but i cant get it to cascade the parts i need for certain cars and years.

in my database i have 6 Comboboxes on an unbound form each one drills down to the next one as it suppose to but when i change to a different make of a car i cant seem to get the parts to show up for that make.

as you may have guessed i have six tables.

Years - YearID, Year
Make - MakeID, YearID, Make
Model - ModelID, MakeID, YearID, Model
Engine - EngineID, YearID, MakeID, ModelID, Engine
ReplacementPart s - ReplacementID, YearID, MakeID, ModelID, EngineID, ReplacementPart
Parts - PartsID, ReplacementPart sID, YearID, MakeID, ModelID, EngineID, Part, PartNumber

My Codes I Have behind Them Is This:

Private Sub EngineCombo_AfterUpdate()
    ReplacementPartsCombo.RowSource = "SELECT ReplacementPartsID,YearID,MakeID,ModelID,EngineID,ReplacementPart FROM ReplacementPartsT WHERE YearID=" & EngineCombo
End Sub
Private Sub MakeCombo_AfterUpdate()
    ModelCombo.RowSource = "SELECT ModelID,MakeID,YearID,Model FROM ModelT WHERE makeID=" & MakeCombo
    ModelCombo.SetFocus
    ModelCombo.Dropdown
End Sub
Private Sub ModelCombo_AfterUpdate()
    EngineCombo.RowSource = "SELECT EngineID,YearID,MakeID,ModelID,Engine FROM EngineT WHERE MODELID=" & ModelCombo
    EngineCombo.SetFocus
    EngineCombo.Dropdown
End Sub
Private Sub ReplacementPartsCombo_AfterUpdate()
    PartsCombo.RowSource = "SELECT PartsID,ReplacementPartsID,YearID,MakeID,ModelID,EngineID,Parts,PartNumber,Price,Core,Store,Phone,City,State FROM PartsT WHERE  EngineID=" & ReplacementPartsCombo
End Sub
Private Sub YearCombo_AfterUpdate()
    MakeCombo.RowSource = "SELECT MakeID,YearID,Make FROM MakeT WHERE YearID=" & YearCombo
    MakeCombo.SetFocus
    MakeCombo.Dropdown
End Sub

If you someone can take the time and look at this and see if you can help me out i would appriciate it very much. Oh I Am using Access 2000 Developers

You should find something to help with this in Cascaded Form Filtering.

8-). Have a real play around with the illustration database. I expect once you've explored a bit you'll find you can adapt the concepts to your own database quite straightforward ly (but if you have any problems still then let us know here and we'll do what we can for you of course).
