A97. A database has a table: tblA which has a single text field, B. It is a
primary field, indexed and no duplicates. It is used as a lookup for table
tblC. A form based on tblA is used to add new records. The Validation Rule:
<>[Tables]![tblA]![b] was made using the expression builder. The rule produces
this error:
The expression [Tables] you entered in the Form control's Validation Rule
doesn't contain the Automation object 'Tables'
If I use simply: <>[b], it rejects everything because as soon as the focus is
moved from the text box to the close form command button, the value in the text
box is entered into the table producing a validation error.
What can I do to allow 'new' records to be entered into the table and to block
all duplicates and to have an error message display to say that the record
already exists?
All help will be greatly appreciated.

The fact that [b] is the PK and has a unique index will already prevent
duplicates. You don't need the validation rule at all.

Your'e correct. But the data entery person doesn't know this because no
message of any type comes up. All that happens is that when you click 'Enter'
or 'Tab' the text box goes blank. The form stays open because it has its own
close command button. They could assume that the data has been entered, which
may not be all that bad since the data is in fact there. Maybe I'm trying to
gild the lily.

Then you must have changed a setting that is preventing it. Attempting to enter
a duplicate value against a Primary Key or a field with a unique index has
always produced an error message for me.

If I did, I don't know what, when why, or how. I've checked every option,
setting and can't find anything that would let me turn warnings on or off.
I'm open to suggestions.

Is there a specific reason why you created a custom Close button? That is why
the record is being discarded silently. There has been a bug going back several
versions now wherein using DoCmd.Close to close a form will silently discard a
bad record instead of alerting the user to the problem. If you were to close
with the X in the upper right you would get an error message.
You can keep the current button if you modify it to save the record before the
line that does the close. The line you need to add is...
DoCmd.RunComman d acCmdSaveRecord

Hi guys,
I would like to setup a validation rule for a database in microsoft
access that restricts data entry so that a certain field can only be
filled in if another field has a specific answer (that is selected via
a drop down list).
Example
Field1 - options are "In" or "Out"
Field2 - options are "Join" or "Not Joining"
