It was working, until I was messing around trying to get the average of the numbers divisible by both 3 and 5 (next on the list) -- needless to say, that didn't work (or I would have kept it in), and not only that -- but now my count goes to <=62. I can't find what the f is wrong. It explicitly states, <=60. What's wrong?

Besides/after that, how do I work out the rest of that list? (How do I find the average of the numbers divisible by both 3 and 5, the average of the sqrts, the sum of the numbers, and the sum of the sqrts?)

Thanks so much.
