Duplicate Values in the index, primary key or relationship

[Denise]

Could you tell me what I need to do to get this not to give me an error?

The changes you requested to the table were not successful because they
would create duplicate values in the index, primary key, or relationship.
Change the date in the field or fields that contain the duplicate date,
remove the index, or redefine the index to permit duplicate entries and try
again.

thanks.

As the error message suggests, your table has data that would invalidate a
key, an index or a relationship.

You'll need to find/fix that duplicate data before re-trying to index the
field(s).

As I learned from my many errors....

I think that the most common case of seeing that message is when entering a
new record which has a PK field value which duplicates that of a previous
record.

Need to run a 'match' query to find duplicate record.

Karl,

I've seen this message lots of times, and 100% of them were the following
case:

I was referring to when the duplicate "record" is not even a record
yet...e.g. someone just entered a new record with a manually entered PK, and,
when you they to move off the new record (i.e. when Access woudl otherwise
enter it) , Access rejects it and gives this error message.
