Yes, the assert stop the calculation.
I tried not to use assert to see what will happen, and try several
combination, but off course, it didn't work.

so the variables I have:

for each individual: GroupID MemberID (1 to 7) WardID (1 to 74) Ward_1
Ward_2 etc Ward_74 that shows distance from ward where the person live to
other 73 wards (0 for the ward he live in).

But, sometimes member of group are only 2 or 3.

Any suggestions?

thanks in advanced
Kartika
