I have a table like this one: | a | b | c | |---+----+---| | a | 2 | 2 | | b | 3 | 7 | | c | -3 | 4 | | d | 5 | 9 | #+TBLFM: $3=$2+@-1::@2$3=$2 Now, I want the value in column c in every row to be the sum of column b so far. I try to achieve this by writing a column formula for column $3 and a cell formula for cell @2$3. Note that cell @3$3 is incorrect whereas all the other are correct. I have tried different formulas and values, and it seems like the incorrect cell is the sum of three cells instead of two as intended. @2$2 wasn't supposed to be part of the sum. Am I doing something incorrectly here? //M.G.
