Hi Natasha

Adjust the following generalisation to match your sheet names and the
columns containing Customer Name and Value
=INDEX(Sheet1!B:B,MATCH(Sheet2!A1,Sheet1!A:A,0))-Sheet2!B1

Where in this example, Column A on both sheets contains Customer Name and
column B contains Value

Hi All,

It has been over 10 years since I did my Excel studies and I've
unfortunately forgotten everything I haven't used regularly. My office has
recently upgraded to Office 2007 (upgrade not being the descriptor I'd
have
chosen!) and I'm struggling with Excel. I've found my way around most
issues,
but I'm REALLY stuck now and suffering Friday-itis on top of it all!

Essentially I have a multi-sheet workbook for my debtors ledger. Each page
has separate columns for the customer numbers, names, total debts in each
age
range (7 days, 14 days etc), totals and lastly contact notes. I've added
another three columns intending to show the difference in 14 days on sheet
30/04/09 and 14 days on sheet 08/05/09, but relating to a specific
customer.

So the formula would need to look at the name in cell B7 on sheet 08/05/09
(for example) and find the same name in sheet 30/04/09 (possibly cell
B20).
It would then check the value shown in cell E7 on sheet 08/05/09 and the
value shown in cell E20 on sheet 30/04/09 and show the dollar difference
in
cell I7 on sheet 08/05/09.

Can anyone help with this? I would be eternally grateful and would worship
the very ground you walk upon!
