Further to a problem that has been really troubling me for a few days.... I am modifying an item on a certain row. At post_change I capture, using a select, the previous and consecutive values. I am doing a substraction of the two from the current and would like to set the difference on the difference column on the second row.
My block looks like thus:
....READ_VALUE | DIFERENCE
---------------|---------------
0 | 0
6 | 6
10 | 4
13 | 3
When for example I change the value 10 at row 3 to 11, at the post_change, I am able to set the former difference of 4 on the same row to 5. I also need to reset the value 3 on row 4 to 2 (ie 13-11) to reflect the new difference. That is what I am unable to do. Please assist...
