Thanks for any help.
Using http://contextures.com/xlDataVal02.html, I have a data validation
dependent on another data validation. So when I change the original data
validation, and then change the dependent data validation, I only get a
choice based upon the original data validation. However, before I choose for
the dependent data validation, if I had a previous choice that wasn't
possible, that value will still remain, even if I choose the original data
validation something that won't have that dependent value. Is there a way to
blank out the dependent if it won't be allowed?
Sorry if that's confusing.

Actually, if I may add to this, how about not 'blanking' it, but setting it
to a default value?
Thanks for any help.

Do you have just 1 primary drop down and 1 dependent drop down? If so, what
cells are they in?

Thanks for offering to help, Valko.
No, I have 2 primary & 1 dependent (or maybe the right way to look at it is
1 primary & 2 dependent). The 1st primary is B1, the 1st dependent is B2, and
the 2nd dependent is B3.

Ok, what you want to do is to clear the contents of the dependent cells
whenever a new selection is made from the parent drop down list.

This requires an event macro.

Select the sheet with your drop downs
Right clcik the sheet tab and select View code
Copy paste the code below into the window that opens

Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
On Error GoTo sub_exit
If Target.Address = "$B$1" Then
Range("B2:B3").ClearContents
ElseIf Target.Address = "$B$2" Then
Range("B3").ClearContents
End If
sub_exit:
Application.EnableEvents = True
End Sub

Close the window and return to Excel

Another option is to make the first drop down list dependent on the
second list too. There's an example he
