Which generates(pun intended) the question, why? You are deconstructing
info into its component parts after the fact, why not just input the
data directly into the fields.

Hmm ... well, that would be a regression, but you're going to have
to show us how to reproduce it. I'm thinking there must be something
odd about the way the table is declared.
