Defaults in Cascaded Combo Boxes

[merry_fay]

Hi, I have a form with 2 combo boxes.

In the first (UCTableYear), I select the Year & in the 2nd (UCTableVersion),
I select the version I want to use from that year from the table Unit Cost
I've managed to set the default for the year to the maximum year in the
table, but I then want the default for the Version to be the maximum version
corresponding to the same year.
This is the code I have:
Private Sub Form_Load()
Me!UCTableYear.Value = Nz(DMax("[Year]", "[unit cost]", ""), 0)
End Sub

Private Sub UCTableYear_AfterUpdate()
Form.UCTableVersion.Requery
Me!UCTableVersion.Value = Nz(DMax("[Version]", "[unit cost]", ""), 0)
End Sub

It's the bit 'Me!UCTableVersion.Value = Nz(DMax("[Version]", "[unit cost]",
""), 0)' which isn't working. What do I need to do to make it set itself to
the maximum available for the year appearing in the 1st combo box?

Thanks

Don't leave the third argument of DMax() empty, but set it to:
"[Year]=#" & Me!UCTableYear.Value & "#"
I am assuming Year is your field name. Not a good choice because it is
a reserved word. Date values need to be wrapped in #-signs.
