I have two access 2007 tables. I would like to use an  append query that only appends records from table1 to table two (append to table) where the SSN and the Consult Date fields are not already in table two (append to table). Any thoughts -- Thanks

Please try to post a sample database and present the *exact* output you need, based on the sample data.

It is not clear if this means the field itself is not present or the field "value" is not present
...etc
<the SSN and the Consult Date fields are not already in table two (append to table)>

The general syntax would be something like:

INSERT INTO Table2 (field1, field2, field3)
SELECT T1.Field1, T1.Field2, T1.Field3
FROM Table1 as T1
LEFT JOIN Table2 as T2
ON T1.SSN = T2.SSN and T1.[ConsultDate] = T2.[ConsultDate]
WHERE T2.SSN IS NULL

Basically, the select statement here uses the Left Join and WHERE clause to identify records that are in Table1 but not in Table2.

Don't know how familiar you are with SQL.  If you aren't (or if you prefer) then you can create a new query graphically in design view and let Access create the SQL statement for you, essentially getting what fyed wrote as the result ...
   Create a new query, add both tables, draw lines between Table1.SSN and Table2.SSN, and between Table1.ConsultDate and Table2.Consultdate, Double Click each line and specify "Include all records from Table1" (the lines change to have an arrow on the Table2 side), drop Table2.SSN down to the grid (by dragging or double clicking it) and specify "Is Null" for the criteria.  Change the query type to "Append" and specify all the fields you want to append.
