Collecting Tabular Input Problem With Update

Why is it that instead of updating the existing record using batch update, it creates a new record?

I am sure I followed the tutorial correctly.

It should update the existing record but what happen on my application is that it creates a new record with new id and a new value of the field I updated.

It really cause me headache. Please help me. Thank you.

Anyone?
