Average Calculating Wrong in the Loop

scoutlikescookies (27)
Hello. I'm wondering if someone can help me fix my code. I have everything set-up, except my output numbers are not calculating correctly. My counts for the number of males and females are off. They are not counting separately. Also, I'm not sure why my youngest person is showing up as 0, when it should be 16. Thank you

I actually got the average working now, but am still having trouble with my other issues.
