Thanks very much let me see whether I understand its logic

I tried

| start | duration |   end | notes |
|-------+----------+-------+-------|
| 08:00 |     1:00 | 09:00 |       |
#+TBLFM: @<<<$2..@>$2=@-1;U::@<<<$1..@>$1=@-1+@-1$+1;U::$3=$1+$2;U

I put the cursor say on the word «start»
And then fire up  C-c C-c, nothing happens. I fire up C-u C-u C-c C-c and it complains because the expression 
points outside the table

| start | duration |   end | notes |
|-------+----------+-------+-------|
| 08:00 |     1:00 | 09:00 |       |
|       |          |       |       |
#+TBLFM: @<<<$2..@>$2=@-1;U::@<<<$1..@>$1=@-1+@-1$+1;U::$3=$1+$2;U

Now C-u C-u C-c C-c gives

| start | duration |   end | notes |
|-------+----------+-------+-------|
| 08:00 |     1:00 | 09:00 |       |
| 09:00 |    01:00 | 10:00 |       |
#+TBLFM: @<<<$2..@>$2=@-1;U::@<<<$1..@>$1=@-1+@-1$+1;U::$3=$1+$2;U

Very very nice, so I can proceed like this.


Thanks a lot!
