I have created a Table that has 13 fields and 2 Primary Keys, e.g. 60 1, 60
2, ... 60 28,
61 1, 61 2, ... 61 28, etc...
I want to create a Form where I can input the Primary Key values to query
the Form to
show the 13 fields assigned to the Primary key pair. If I create 2 Combo
boxes I can only
get the see the assignments for the first Primary Key, or only for the
second Primary Key.
I can't see how to get the lookup to use both Primary Keys.
appreciate any help

Just for the record <pun intended>, a Record can have either no Primary Key
or one Primary Key. What you describe is a multi-field Primary Key, that is,
a single Primary Key composed of two Fields.
Create an unbound Combo Box, showing all the values of the first Field of
your Primary Key. Create a second unbound Combo Box, with a query for Row
Source that uses the first Combo Box value as criteria for that Field, and
shows the values of the second Field of the Primary Key to be selected. In
the After Update event of the first Combo Box, Requery the second Combo Box.
In the AfterUpdate event of the second Combo Box, use the contents of both
Combo Boxes to construct the WHERE clause, or WhereContition argument of a
DoCmd.OpenForm (or DoCmd.OpenRepor t).
In my "linked Combo Box searches" I set the Enabled property of the second
Combo Box to No in Design View, and enable it in code in the AfterUpdate
event of the first Combo, just prior to Requerying. That prevents the user
from entering the second Field first and causing confusion (though if you
are careful, you can make it work "going either way").

Hello all,
I just discovered something (stop me if you've heard this before....) that
was causing me a significant performance hit when opening a form with
subforms.
To speed up loading the form, I set the rowsources of its, and its
subforms', combo boxes in the "Enter" events of the combo boxes. That's the
standard trick for not loading the rowsource unless/until the user actually
needs the combo box. For example:

Hello,
I am trying to create a chart whose underlying query is linked to 2
combo boxes on the same form.
I want to pass the values from the combo boxes into the chart query to
allow the chart data to be manipulated easily.
The combo box uses "Row Source Type" = Table/Query. The "Row Source"
references a query to extract a distinct list of data.

I have a question about how to add and then use the "All" selection in
a combo box. I am trying to figure out how to:

I am working on a form that uses 3 text boxes and 3 combo boxes.
