Can any body help????
Bob Phillips kindly replyed to my original post with this

=IF(ISNUMBER(MATCH("value",A:A,0)),"value"&INDEX(B :B,MATCH("value",A:A,0)),"
")
But it didnt work, due almost certainly to a poor explaination from me.
Original post now lost in annals of new posting.

Layed out below is I think a better explaination.

What we are dealing with is monthly job sheets (1-12) for one customer
contained in Book1. There is 3 separate identical sections on each sheet
relating to 3 differant staff members, each section is Col A:Y by 25 rows.
Col A contains dates displayed as 1st, 3rd etc. Col B contains a text
description of work carried out. Col C:X contains financial break down of
work carried out. Col Y contains Total in £ of C:X

E.g

Book 1 (could be on any one sheet #1-12)

Col A Col B Col C:X Col Y
2nd aa 5+5 £10
6th bb 2+3+5 £10
17th cc 5+5 £10
-----------------------------------
1st dd 3+2+5 £10
6th ee 4+6 £10
10th ff 2+8 £10
----------------------------------
2nd gg 8+2 £10
6th hh 7+3 £10
17th ii 1+9 £10

I am trying to produce a edited monthly Invoice from the above data in Book 2
Sheets 1-12 but displayed as below

1st dd 10
2nd aagg 20
6th bbeehh 30
10th ff 10
17th ccii 20
Total £ 90
