Hmmm, I've read up quickly on crosstab queries, and am not entirely sure that is what you need.
So, You can either create two queries, one that will count gender, one that will count nationality, then show them in a report or display them in a form, OR create one query If what you want is say:
There are 4 females, 2 are English, 1 is Russian, and 1 is French
and 3 males, 1 is English, 2 are Russian
Then the query would look like this:
Female, English, 2
Female, Russian, 1
Female, French, 1
Male, English, 1
Male, Russian, 2
