[AccessD] Duplicates on Two Values

Virginia,
Did you try Rocky's suggestion? Just tried it - works fine.
Private Sub Field1_BeforeUpdate(Cancel As Integer)
    If Field1.Value = Field2.Value Then
        MsgBox "Dublicate values for Field1 and Field2 not allowed"
        Cancel = True
    End If
End Sub
Private Sub Field2_BeforeUpdate(Cancel As Integer)
    If Field1.Value = Field2.Value Then
        MsgBox "Dublicate values for Field1 and Field2 not allowed"
        Cancel = True
    End If
End Sub
Don't know why this shouldn't do for you - perhaps I'm missing something?

In the before update event of each field check if field1 = field2.  If yes,
then message to user delete contents of the field being checked.

Number 3. ItemName can be repeated & so can the ItemDesc just not together
in the same record. 

 

For example, Paper comes in several different kinds, it can be Legal Paper,
Lined Paper, Construction Paper, etc. I just don't want them entering Legal
Paper twice. If it has already been entered, I would like it to take them to
that record, but at this point just letting them know Legal Paper has been
entered would be ok.

 

I am having a problem checking ItemName AND ItemDesc, especially since they
are text fields.

 

ItemName: Paper

ItemDesc: Legal

 

ItemName: Paper

ItemDesc: Lined

 

ItemName: Book

ItemDesc: Legal

 

ItemName: Book

ItemDesc: Lined 

 

********

Is it the case that you have three checks to make?

 

1) Is ItemName already being used in an existing record?

2) Is ItemDesc already being used in an existing record?

3) Is ItemName = ItemDesc in the current record?
