Default Query yes/no data type

I am developing a database which has a yes/no data type field in it.
A sample of the table is below:

Customer Name - text
Customer Still Active - yes/no data type

I need to develop a query which creates 2 seperate tables from the master table which are based on whether a customer is still active or not.
However, i am having problems creating a query in which the main field of query is the yes/no data type. I've had a host of erros - any help in this area would be more than welcome.

thank you

The Yes/No type field is a boolean type. And the True value of booleans in Access is "-1", not "1" as in many other languages.

Need something like:
If StillActive=-1 then append to table1
If StillActive=0 then append to table2
Do Nothing, must be a null value.
Could do 2 separate MakeTable queries:
1. Select all where StillActive = -1
2. Select all where StillActive = 0

Sanity Check: Total Records in Table1 and Table2 = Total Rercords in original table. Any difference in count = Null values in StillActive.

...which is why you should you the intrinsic constants TRUE and FALSE whenever you wish to do tests of this nature.
