It's good to give your email a subject line that describes what you're doing.

The indentation below is all screwed up. I think this is because you
posted in html email. It is better to use plain-text email when
sending to this list so that the code doesn't get garbled.

All of the lines below are executed repeatedly in a loop

including the line above that sets count to 0.

So when you increment count above it has always been set to zero
first. You need to set count to zero once before the loop. Then
increment it by one on each iteration of the loop (if the point is in
the circle).
