how do i make it so that data entered in the gender column can only be M or F and then create a button that calculates the amount of Males and Females?

Answer 1

Select Column E (entirely)
Menu Data-->Data Validation-->Settings Tab -->
    Allow: List
    Source: M,F

You'll get a combobox at each cell of row E. To get the number of Males, type this formula in any cell of the worksheet:

=COUNTIF(E:E, "M")

Similarly for F emales.
