From: Dave on 6 May 2010 16:02 Hoping someone can help. I have a sheet that has 12 months of data going across 12 columns. Each column has a heading for each month i.e 1, 2 ,3 ... There are multiple rows of data. I need a formula that will sum the columns of data based on the month that is entered in cell A1. For example, if I enter 5 in cell A1, I want the YTD formula to add up only the first 5 months of data. Thanks in advance for any help.
From: Bernard Liengme on 6 May 2010 16:11 My worksheet has 1,2,,3...12 in B1:M1 In the 20 rows below I have data In A1 I enter a number, say 5 In A2 I have =SUMPRODUCT((B1:M1<=A1)*B2:M21) This sum all the data for the columns having number 1 thru 5 in row 1 best wishes -- Bernard Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme "Dave" <Dave(a)discussions.microsoft.com> wrote in message news:4F460C6A-753C-4CEC-8677-89D9222A4592(a)microsoft.com... > Hoping someone can help. > > I have a sheet that has 12 months of data going across 12 columns.

From: Dave on 6 May 2010 17:01 That worked great for summing up all the data in the range. One more question. I also need to have a total for each row of data. What formula would I need to use on each row to total each row based on the month keyed into cell A1?

I assume you want to sum everything that is in one row: =SUM(OFFSET(B2,,,1,A1)) Change B2 to the cell that has the data for January in the row of choice. --ron |
