Should add a caveat to the above suggested formula.

It is very resource intensive.

Wouldn't recommend it for use on ranges in excess of 5,000 cells.

Say headers are in A1 to D2, and data starts in A3.

Enter this in D3:

=IF(B3="LR",SUM($C$3:C3)-SUMIF($B$2:B2,"LR",$D$2:D2),"")

And copy down as needed.

Dear Sir,

I have the following table to be sum up in block as illustrated.

A B C D


Block
Serial No Border Amount Sub total
1 CX2145 LR 250 250
2 CX2146 550
3 CX2147 620
4 CX2148 420
5 CX2149 LR 200 1,790
6 CX2150 650
7 CX2151 210
8 CX2152 LR 140 1,000
9 CX2153 360
10 CX2154 480
11 CX2155 860
12 CX2156 LR 960 2,660


Column B is the block separator "LR" that divides the block to be sum up.

May I know what formula I must input at cell D1 and copy downwards to get
the answers?

Thanks

Low
