Hi

Sorry if I was unclear. The master sheet contains a number of
calculations
of year to date based on the monthly figures on the monthly sheets.
Therefore in January for cost centre AAAA I will do a lookup of the
expenditure for January and so place it in the correct cell. February's
submission will go in the next column and the master sheet will
recalculate.
All is OK until the submission in March contains an entry for anew cost
centre ie ZZZZ not on the master sheet and therefore this expenditure will
not be included in the calculations on the master sheet. Therefore I need
to
identify new codes and add them to the master sheet. These contain
thousands
of lines and therefore I need to automate this process. I hope that
clarifies my objectives.

Thanks

Maybe you could just copy the whole thing. Wouldn't that be the same as
comparing?
If desired, send your file to my address below. I will only look
if:
1. You send a copy of this message on an inserted sheet
2. You give me the newsgroup and the subject line
3. You send a clear explanation of what you want
4. You send before/after examples and expected results.

Hi

In Excel 2003 I have a spreadsheet listing a large number of cost
centres.
Each month I am given a list of the cost centres and expenditure
against
them, which I want to use a look up to populate in to a master
spreadsheet.
However, during the month new cost centres could have been created.

What I would like to be able to do is run a macro against the monthly
return
and compare the codes contained in it to the codes already listed in
the
master sheet. If there are any new codes not already in the master
sheet
I
would want them added to the existing list so that the master remains
complete. Any suggestions on how to achieve this would be welcomed.
