Duplicate Records

Please Help!!!

I've got three seperate tables in my database.

Table #1
Document#(PK)---------|
Document Title |
|
Table #2 |
Document#-------------|
Document Version
CC#-------------------|
|
Table #3 |
TS#(PK) |
TSEffectiveDate |
CC#(PK)---------------|

(PK) = Primary Key.

I created a query using:

DocumentID(Table #1)
Document Title (Table #1)
Document Version (Table #2)
CC#(Table #2)
TSEffectiveDate (Table #3)

My problem is:

I'm getting duplicate records and I don't know why. There
are no duplicates in any of the tables creating the
query. If I take the option TSEffectiveDate(Table #3) off
the query I get no duplicates. As you can see what
connects Table #2 to Table #3 is the CC#. I need the
TSEffectiveDate in my end result.

Can someone advise.

Thanks in advance.

You described the tables, but left out the relationships. From your table
descriptions, I'm guessing that one document (table1, Document#) can have
one-to-many ?versions (table2).

This would be one explanation for why you get multiple rows per Document#.
 
Jeff:

Here are my relationships:

Table #1
The ultimate idea is that the Document# (Table 1) only is
entered once but their is multiple versions of the same
document (table #2). The TS#EffectiveDate identifies the
date for all document versions created by the TS#. Since
multiple documents and document versions can be created by
the TS# and associated CC# (Table 3). Table #2 can only
have one document version per TS# and associated CC#.

Hope that makes sense.

Thanks again.

If I'm understanding your description, you have a one-to-many relationship.
You are running a query that joins the one-side table to the many-side
table. I would EXPECT to see multiple rows per one-side row.
