yes/no data type custom

[jen]

Hi.
In the format box for a field, instead of Yes/No, I have entered
;"Male";"Female"
And I have changed the Lookup to Text box.
But in datasheet, only Female appears and cannot be modified. If I put Male
I get this message

-------The value you entered is not invalid for this field
For example, you may have entered text in a numeric field or a number that
is larger than the fieldsize setting permits -------

Can someone please tell me what I'm doing wrong.
Thanks

What happens if you try to enter 0 or -1?
