get number of points in a hotspot

How could I get the number of points in a hotspot? I would like to add new points to a hotspot like this:

set(hotspot[h2].point[current_num_of_points].ath, get(h));
set(hotspot[h2].point[current_num_of_points].atv, get(v));

but I do not know what is the current_num_of_points.

Thanks

got it. I was pretty rusty after xmas break

hotspot[name].point.count
