The primary key's only purpose is to uniquely identify the row in the table, it should have no other meaning.

FirmaInfo[i][IDBiz] = cache_get_field_content_int(i, "IDBiz");

You already have that. When referring to the biz in the script, use "i", when referring to the row in the database use "IDBiz".
