New to stata need help.

[Sarmad Latif]

hi my final year project involves analyzing bicycle crashes in my state, im new to the software stata and would like some help. ive downloade the excel file but cant seem to filter male and females among bicycle users and non bicycle user. ive attached it and what i basically need is a way to filter the males and females amongst bicycle and non bicycles users to find out. this will not only help in this but can allow me to filter other variables too.
Thanks
