Hi

The following works nicely 

#+begin_src 
#+NAME: table1
| Name   | Ex1 | Ex2 | Ex2 | Ex4 | Ex5 | ResSh1 |
|--------+-----+-----+-----+-----+-----+--------|
| Smith  |   2 |   3 |   4 |   6 |   7 |     22 |
| Miller |   2 |  10 |   1 |   1 |   5 |     19 |
| Wick   |   1 |   2 |   3 |  10 |   2 |     18 |
#+TBLFM: $7=vsum($2..$6);f2


#+Name: final
| Name   | ResSh1 | ResSh2 | Total |
|--------+--------+--------+-------|
| Smith  |     22 |        |       |
| Miller |     19 |        |       |
| Wick   |     18 |        |       |
#+TBLFM: $2=remote(table1,@@#$7)
#+end_src


However if in table1 there is an empty entry in the relevant column,
remote copies it as 0

#+begin_src 

#+NAME: table2
| Name   | Ex1 | Ex2 | Ex2 | Ex4 | Ex5 | ResSh1 |
|--------+-----+-----+-----+-----+-----+--------|
| Smith  |     |   3 |   4 |   6 |   7 |        |
| Miller |   2 |  10 |   1 |   1 |   5 |     19 |
| Wick   |   1 |   2 |   3 |  10 |   2 |     18 |
#+TBLFM: $7=if("$2" == "nan", string(""),vsum($2..$6)); E f-2


#+Name: total
| Name   | ResSh1 | ResSh2 | Total |
|--------+--------+--------+-------|
| Smith  |      0 |        |       |
| Miller |     19 |        |       |
| Wick   |     18 |        |       |
#+TBLFM: $2=remote(table2,@@#$7)
#+end_src

Any idea how to obtain an empty entry instead of 0?

Thanks and regards
