hmm
the perfect solution would be that if u do doubble click on B3 a
"new-small-tiny-excel" opens and that u can type in there
A
1 100
2 20
3 -10
4 -15

and that B3 than has the vaule 95
the problem is that tere could be 20-30 of these B-fields so a connection to
another table is tooo complicate
u understand the problem?

kind regards
mario
