hi,all. I have a orgtbl like the following, | # | 2 | a | | # | -2 | abc | | # | 5 | abc | | # | -3 | a | |---+----+-----| | | | | | ^ | x | |
and i want to sum the second column which the corresponding third column's values="abc" to variable x. (in this example $x = -2+5 = 3). what Formula syntax for Calc/Lisp can achieve this,please. thanks.
