I have the following code in the afterupdate event of a field called actual
Pit. Once the pit is selected it shows only the cost and material from that
given pit.

Private Sub cboactpit_AfterUpdate()
Dim nsql As String
nsql = "Select Costperton,Material " & "FROM materialcostsheet " & "WHERE
pit=""" & Me.cboactpit & """ " & "ORDER BY material"
Me.cbocost.RowSource = nsql

End Sub

However - it functions and looks nice but not doing Exactly what I want it
to do


It display the costperton, than the material in the drop down obviously in
order by material

Don't know if this is possible but I would like the user to type in the
material Name and it to scroll to the given material - BUT THE COSTPERTON
SHOULD BE STORED IN THE FIELD - One is text the other number field not sure
what i need to do or if this is possible.

Thanks,
Barb

No, it shouldn't.

Storing derived data such as this in your table accomplishes
three things: it wastes disk space; it wastes time (almost
any calculation will be MUCH faster than a disk fetch); and
most importantly, it risks data corruption. If one of the
underlying fields is subsequently edited, you will have data
in your table WHICH IS WRONG, and no automatic way to detect
that fact.

Just redo the calculation whenever you need it, either as a
calculated field in a Query or just as you're now doing it -
in the control source of a Form or a Report textbox.
