Lookup Field in a Table set to required

[samdev]

I have set up a table with a few fields that are set to
required....all work fine except the fields that are Lookup from
another table.

What am I forgetting to set?

Thanks!!

What you are forgetting is to tell us more about what is not working.

Presumably you are speaking about a form, and for the lookup fields
you have a dropdown that lists the values from the lookup table. So
far that is pretty standard. How does your implementation differ from
that?
You do have 2-column dropdowns, right? A hidden ID value and a visible
Description value. Several examples of this in the Northwind sample
application.

Sorry....

I have set the field to required at the Table level and yes it is drop-
down as you described and it allows me to input a complete record even
if I have left the lookup field blank. Other fields that I have set to
required, if I leave blank, Access will not allow me to complete/save
the record. I need all required fields to work properly - so not allow
a user to save the record unless all required fields are complete.

Thx,

I don't think it quite works that way. You may need to double-check.
If a field does not allow nulls, it doesn't. It MAY accept an empty
string, but not null. Whether it is a lookup field or not has no
bearing on this.
Do you have a default value on this field?

If you truly mean they are defined as LookupFields in the Table, back slowly
away, making signs to ward off evil.

Replace the LookupFields with a Foreign Key to the Table where key and value
for the Lookup is stored. Now, if you insist on playing novice user and
looking at the datasheet view, you'll see the foreign key value, not the
descriptive information (but you'll be seeing exactly what is stored) and
you'll know you can create a query joining the two tables to see the full
information.

What you won't get are the "varagies and eccentricities" of Lookup Fields
which store one value and display another... for anyone who's not doing a
novice-level database and needs to flatten their files in the tables, Lookup
Fields end up being more trouble than they are worth, and should be replaced
with Lookup Tables, as I described above..

Be sure to heed Larry's advice. It will save you headaches and
bottles and bottles of asprin.

Thanks - sorry for all the confusion - I am using lookup tables! I'm
still having some issues but most I have worked out.

Re: Lookup Field in a Table set to required

The question is not the use of lookup tables, but rather using the
lookup tables option in the actual table as opposed to using a lookup
query/table for a dropdown on a form.
