It can be the "call" of school...
for example ;
I inputted Name of School: TAPILON NATIONAL HIGH SCHOOL, automatically the facility ID, municipality and province will appear also and
All Students who in school in TAPILON NATIONAL HIGH SCHOOL will be added to the form at the same time the rows data will be added to their respected name including the following: household_ID, member_ID, last name, first name, middle name, extension name, gender, birthdate, age and grade level codes.

I hope...this explains for good...

thanks..
