Find a row give me a column
 

Hello Lovely Excel People (flattery works sometimes)
OK so I have a spreadsheet (I know amazing)
With lots of data.
Column A is period so 200908 is August 2009
Column D is a Customer Number.
Column Y I want to be Column T minus Colum T of Customer in "D" in Row A -1
So for instance we are using line 3500
in column Y it would be D3500= 12345
Find 12345 in the spread sheet where Column A = A3500-1

OK anyone have any ideas or any questions to make this actually make sense?

Sorry. Don't think that makes any sense. Lets try again.

I have a large amount of data.
Everymonth the data starts again with Column A incrementing by one from
200908 in August to 200909 in september.
We want to know the difference between the number in Column T from august
and column T from September.
So how do we search through the spread sheet for first the customer number
in Column D and then the previous period which is A -1

Hope that helps.

Hi Mark, what you need to know is the limits on your periods i.e. August runs
from row 1 to row 500 and then september from row 501 to say 1200. Then you
use the following formula to work out column T difference where 12345 is the
customer number you are interested in.

=VLOOKUP(12345,$D$501:$T$1200,0) - VLOOKUP(12345,$D$1:$T$500,0)
