Why am I getting a divide by zero error

["tosk" <tosk@xxxxxxx>]

<<Actually, that kind of DBZ error I understand.  My
problem is when I get a divide-by-zero message when
no division is taking place.  The following line is what
causes the problem:

If CMO(n) > CMO(n)[1]


Are you sure the error is not occurring within the CMO function itself?  I
don't know how CMO is constructed but it would appear that CMO(n) is causing
it.
