Difficulty with N_ELEMENTS command [message #79239]

Hi.

I'm trying to create an array of the number of elements that satisfy a
certain criterion as below.

FOR m=0,nyears-1 DO BEGIN
exceed_freq(m)=N_ELEMENTS(WHERE(precip_day(m,*) gt smoothed(*)))
ENDFOR

The problem I have is that for some years in my program there are no
elements that satisfy this criterion, however the value returned in
the array 'exceed_freq' is 1 instead of 0.

I would appreciate any comments.

Thanks,
Andrew
