Hi well there is no School.subjects.teachers in your case.
You should do something like this :
count = 0
@school.subjects.each {|s| count += s.teachers.count}
It is possible that you could use inject above to shorten it a bit, but not
sure about that in this case.

OK,
But right now, i have--
Schools has many subjects, subjects has many teachers
So instead of-- @totalcount = @school.subjects.count (that just
cuonts how many subjects are in the school)
how can i count the teachers in that school? maybe something similar
to @totalcount = @school.subjects.
