# Excel/Excel 2010 - formula problem

Question
Hi

I am trying to find a solution to extract data from a table so long as two criteria match but one of those will change from month to month.

So from the basic table below, I will select the month of March from a drop down listing. Then I want my formula to give me the data by account for that month selected.

My problem is I don't know how to arrange the formula so that the months column is picked up automatically without having to change the formula each month to pick up the next applicable column.

The table of data will not be able to be edited to add in new columns.

I hope this makes sense (I have tried to word this as best I can).

Many thanks
Ruth

Select Month from drop down      Mar
Table of data.

Ac No      Jan   Feb   Mar   Apr

1000      52.6   426.8   2.6   5.7
2000      3.95   100   4587   200
3000      -36   5   1570   5
4000      33   145   11   5367

Required output when March is selected from the drop down.

1000      2.6
2000      4587
3000      1570
4000      11

assume the month names are in the first row and the dropdown is in M2  and the account numbers are listed in M3 to M6

in cell N3:
=OFFSET(\$A\$1,ROW(\$A2)-1,MATCH(\$M\$2,\$1:\$1,0)-1,1,1)

then drag fill that down column N.

The A2 in the row function will return a 2 as the second argument to the Offset function (minus 1 from that give a 1).  The offset from the first argument in the offset function is zero based.  so offset(\$A\$1,0,0,1,1) is A1.  Offset(\$A\$1,1,0,1,1) is A2  and offset(\$A\$1,0,1,1,1) is B1 just to illustrate.

That assumed it is picking up accounts in the same order as listed.  If you want to match the account number in M3 then

N3:
=OFFSET(\$A\$1,MATCH(\$M3,\$A:\$A,0)-1,MATCH(\$M\$2,\$1:\$1,0)-1,1,1)

so there is a match in both the row and column position.

Then select N3 and drag fill down column N.

Tested in with the stated situation and worked for me.
