Anyone familiar with SPSS?

[BigToque]

I'm running a crosstabulation of two variables and I want to get rid of my "dont know" answers.

How do I do this?

You'll have misleading results if you drop valid responses, since the overall percentages will change, but you could add a couple of recoded variables where don't know is changed to missing data.

(Don't ask me how, I haven't used SPSS this century.)

You could also just paste into Excel and delete that column / row, then the displayed results are still valid just incomplete.
