#### computing the difference of a column in the current row from the column of the preceding row

```Hello,

a user asked me if we can solve following problem:

we want to compute the difference (delta) of a column in the current row
from the column of the preceding row.
My first solution signs where:
create a computed field (small_function_result) that takes the value from
the preceding row:
small(value, value, cf_getrow for all); where cf_getrow is a computed field
like this:
if(getrow()=1,getrow(),getrow()-1)

create a computed field (Diff) that computes the difference:
value-small_function_result

My results should look like this:
Row    Value        cf_getrow  small_function_result  Diff
1          5123         1                 5123                             0
2          5126         1                 5123                             3
3          5132         2                 5126                             6
4          5134         3                 5132                             2
and so on

But it seems that the small-function doesn't work dynamically, because i got
following result (the difference
is an cumulative value) (the computed field cf_getrow contain the right
values !!!!!):
Row    Value        cf_getrow  small_function_result    Diff
1          5123        1                  0
0
2          5126        1                  5123
3
3          5132        2                  5123
9
4          5134        3                  5123
11
and so on

Has anybody some ideas ?

Thanks

Michael
