Hi,
this might be an obvious thing, but still I'm biting on this for some time:
Let's pretend I want to have a table with 3 columns.
The first and second should each hold an integer value, the third should
hold the sum of column1 + column2 as an integer.
The idea behind this table should be that the sum is automatically
updated, each time I change one of the values in either of the first two
columns.
Best regards,
alex
