I see that you have been given a solution elsewhere using vmean but you could also consider adding "N" to the expression (i.e. after ;E). This would make the empty entries be treated as having a 0 value so your check for nan would no longer work but you could always check for 0... The following works: | Name | E1 | E2 | E3 | E4 | Res | |+++++-| | Entry1 ||||| NP | | Entry2 | 10 | 20 | 30 | 40 | 10 | | Entry3 | 10 || 20 | 30 | 6 | #+TBLFM: $6=if("$2" == "(0)" , string("NP"),($2+$3+$4+$5)/10);EN HTH, eric -- Eric S Fraga via Emacs 27.0.50, Org release_9.1.6 signature.asc Description: PGP signature

I meanwhile circumvent the problem by | Name | E1 | E2 | E3 | E4 | Pre | Res | |+++++-+-| | Entry1 ||||| 0 | NP | | Entry2 | 10 | 20 | 30 | 40 | 100 | 10 | | Entry3 | 10 || 20 | 30 | 60 | 6 | #+TBLFM: $6=$2+$3+$4+$5::$7=if("$2" == "nan", string("NP"),$6/10);E But your solution is much more elegant.

Maybe the format of the table was distorted. | Name | E1 | E2 | E3 | E4 | Res | |+++++-| | Entry1 ||||| NP | | Entry2 | 10 | 20 | 30 | 40 | 10 | | Entry3 | 10 || 20 | 30 | nan | #+TBLFM: $6=if("$2" == "nan" , string("NP"),($2+$3+$4+$5)/10);E The column of reference is E1 per default, which is the second one. The row labeled Entry1 gives the expected result, NP, since its E1 entry is empty but in the row labeled Entry3 E1 is not empty, so the second part of the statement should be applied resulting in 6, but it does not it results in nan, which I don't understand. The fact that E2 ($3) is empty should be irrelevant here, but it is not. On the other hand | Name | E1 | E2 | E3 | E4 | Res | |+++++-| | Entry1 ||||| NP | | Entry2 | 10 | 20 | 30 | 40 | 10 | | Entry3 | 10 | 0 | 20 | 30 | 6 | #+TBLFM: $6=if("$2" == "nan" , string("NP"),($2+$3+$4+$5)/10);E Gives the expected result, that is adding 0 to E2 in row Entry3. I am puzzled Uwe

What I meant is this. Take the following simple table | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 | 10 | 30 | 40 | 50 | || Entry2 | 10 | 20 | 30 | 40 | | #+TBLFM: $6=($2+$3+$4+$5)/10 C-u C-u C-c C-c leads to | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 | 10 | 30 | 40 | 50 | |13 | Entry2 | 10 | 20 | 30 | 40 | 10 | #+TBLFM: |$6=($2+$3+$4+$5)/10 Now for any new entry I want to have in the 6th column NP if the entry in the second column (not the whole column) is empty. | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 | 10 | 30 | 40 | 50 | |13 | Entry2 | 10 | 20 | 30 | 40 | 10 | Entry3 |||| || | Should lead to | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 | 10 | 30 | 40 | 50 | |13 | Entry2 | 10 | 20 | 30 | 40 | 10 | Entry3 |||| || NP | How can I achieve that? The following works well | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 ||||| |NP | Entry2 | 10 | 20 | 30 | 40 | 10 | #+TBLFM: $6=if("$2" == |"nan" , string("NP"),($2+$3+$4+$5)/10);E although the second column is *not* empty, but it is empty for Entry 1. But fails if there is a row like this | Name | E1 | E2 | E3 | E4 | Res | |+++++-| Entry1 ||||| |NP | Entry2 | 10 | 20 | 30 | 40 | 10 | Entry3 | 10 || 20 | |30 | nan | #+TBLFM: $6=if("$2" == "nan" , |string("NP"),($2+$3+$4+$5)/10);E Uwe
