The title doesn't quite convey what I'm wanting to do but here's an example.

I have data grouped according to a key field in "A" and I have descriptive
data in "B". That descriptive data can actually be parsed into a possible 5
subsets of data. But some "B" fields don't contain all 5 subsets.

For instance PurTexWhoDis15 might mean, Purchased, from Texas, Wholesaler,
Discount of 15%. But some records in my keyed group might only read PurTex.
They should all read PurTexWhoDis15.

I can run a LEN in column "C" and sort by A ascending and then by C
descending and then write an if statement that says if C4 < C3, B3,""). That
works the first time Len is 6 for C4 and Len is 14 for C3. But is the Len of
C5 is 8 also, it just copies the 6-character expression found in B4.

HERE's What I'm getting (and the spaces to separate the key-sorted data are
in the spreadsheet)

KEY CODE PRODUCT
1111 PURTEXWHODIS15 1111-00
1111 PURTEXWHODIS15 1111-14
1111 PURTEX 1111-05
1111 PURTEX 1111-22
1111 PUR 1111-80


2222 PURTEXWHODIS10 2222-01
2222 PURTEXWHO 2222-04
2222 PURTEXWHO 2222-10
2222 PURTEX 2222-15


Here's what I want to end up with:
