Excel functions

I want to write a function which does an "if" and an "and" to look at two cells and dependant upon their contents return a choice of two characters.
I am trying to sort a list containing DOB and sex to return a count of all males and females between the age range of 20-30.

We need a better description of your worksheet layout - i.e. exactly what you have and where - and what you are trying to achieve. From your brief outline I would say that you need a SUMPRODUCT, not a combination of IF and AND.

For example with F or M in A2:A11 and ages as integers in B2:B11


will returm the number of females aged 20-30.

Thanks Vog - have never seen a formula with dashes in it before but it works great. I am doing a census and was trying to identify how many individuals in a list of 205 were male or female and what age they were between the age ranges of 8-16. I had done a number of ifand statements to achieve this but yours works far better.

(A2:A11="F") returns an array of True or False values, similarly (B2:B11>19) and (B2:B11<31) return arrays of Boolean values. The -- is used to coerce these from True or False to 1 or 0 respectively. SUMPRODUCT can then count the instances in each of the three arrays where 1 occurs in the same place. An alternative is


but this is somewhat more 'expensive' in terms of computation. This is only really noticeable when dealing with large arrays.
