Help with validation feature`

[Don Sealer]

I've got a validation rule that says something like =xx or xxx or zzzz.
Though I may not have described it well it does work fine and that is really
not my question.

Here's what I'd like to do. Let's say that I choose zzzz, I'd like for
a particular control (or text box) in my form to become required. At other
times, if xx or xxx is inputed it would not be required. Is this possible?

Thanks, and as always, further explanatiions will be forthcoming,
Don..........

Open your table in design view.
Open the Properties box (View menu.)
Beside the Validation Rule in the Properties box, enter:
([Field2] Is Not Null) OR ([Field1] Is Null Or [Field1 <> 'zzzz')

To compare fields, you need to use the *table's* validation rule (the
properties box), not the Validation Rule for a field (in the lower pane of
the table design window.)

This might best be handled in the form's BeforeUpdate event. Ex:
IF Me.Text0 = "zzzz" And IsNull(Me.ParticularControl) Then
msgbox "The field ParticularControl is required."
Me.ParticularControl.SetFocus
Cancel = True
Endif

Thus, if "zzzz" check the value of the control and if blank require
something.

Thanks for the quick reply. However I'm not understanding either of the
replies. I think I understand what your saying althoug I'm not sure how to
enter or write what you are telling me. Also now that I have read your
replies and re-read my question I think I need to add more detail, which I
probably should have done in the first place.
This part of my database has three objects(?).

Tables:
Red Tag DC
Resolution

Form:
Red Tag DC Form

In the form is also a field (Combo Box) called "Resolution". The Resolution
field (combo box) has several options, one of those options is "Use As Is".
Also in the form is a field (Text Box) called TDA#.
Both of these fields are "not required".
If someone enters "Use As Is" into the Resolution field (combo box) I'd like
to have the TDA# field become "required".
Is this possible? Is it still as you have replied to me originally? If so
could you give me some more help in entering the information necessary to
make it happen? If it requires other code would you please provide the
detail?
If it can't happen at all thanks for your interest and I apologize for
wasting your time in the first place.

I'll explain why I'd like this. The only way product can, or should, be
used when designated as "Use As Is" is with a TDA. So making this field
"required" when someone enters "Use As Is" would ensure that this
information is recorded.

I hope I've explained this better and once again I apologize for not doing
this in the first place.

Exactly as in the previous reply, set the Validation Rule on your *table*
as:
([TDA#] Is Not Null) OR ([Resolution] Is Null Or [Resolution <> 'Use As
Is')

The rule can be satisfied two ways:
If TDA# is not null, it's happy.
Otherwise, it happy is Resolution is not 'Use As Is'.

Thanks again,
