It would help to understand better if you can paste two blocks of data.

You may send the complete file if it does not contain confidential data.

I have a database export file that includes multiple (1100+) blocks of
data in a standard format.

Per block, the format is:
-- The first column is a merged cell of 9 rows, with the unique
identifier for the data block.
-- The next five columns form a sub-block of data related to that
item in the first column.
-- This sub-block has a format of:
-- Row 1: Titles of the five columns in the sub-block.
-- Rows 2-8: data (column 1 contains the Titles/names for each
row).
-- Row 9: Totals for each column's worth of data.

I want to go through the whole export file (spreadsheet), summing
particular cells in Row 9,
based on the unique identifer in column 1.

Can I use VLOOKUP and SUMIF for this? (If so, how? If not, then how do
I find the blocks I
want to use for my calculation and then choose the correct cell in Row
9 for that block?)

I had thought of taking each row and separately copying it to form a
single row per unique
identifier, and then using VLOOKUP and SUMIF without the added fun of
navigating the sub-
block, but my preference is to not have this intermediate reformatting
step.

A related question: can I use PERCENTILE if I have such non-contiguous
blocks of data?

Any help/insights/commands/etc. would be greatly appreciated.
