Hi

I have a spreadsheet and it has data in columns A-K and what im trying to do is at every change of number in column A, I need to do an autosum of the values of data in column I and input the total into column J .

Lets say I have the same number in A1-A9 and I have values in Column I, When the number changes in A10 I need the data in I1-I9 all added together and then a total put in J9.

I then need this to repeat down the sheet. The same number in column A varies depending on how many entries there are.

Any ideas?

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.

Please try this formula. Put it in cell J2 and copy down. The principle is if Col A Changes and the next cell in Col A isn't blank the sum the values above.

=IF(AND(A2<>A3,A3<>""),SUM(OFFSET(J2,-(ROW(J2)-IFERROR(MATCH(1E+300,$J$1:J1),1)-1),-9,ROW(J2)-IFERROR(MATCH(1E+300,$J$1:J1),1),1)),"")

Really appriciate that.

Can I just ask is my formula correct if I want to do the same as originally stated but using column B as the one to look for changes in.

=IF(B1<>B2,SUMPRODUCT(--($B$1:B1=A1),$I$1:I1),"")
