I have a table like this one:<br><br>| a |  b | c |<br>|---+----+---|<br>| a |  2 | 2 |<br>| b |  3 | 7 |<br>| c | -3 | 4 |<br>| d |  5 | 9 |<br>#+TBLFM: $3=$2+@-1::@2$3=$2<br><br>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&#39;t supposed to be part of the sum. Am I doing something incorrectly here?<br>
