om...
I encounter a Excel problem, let me explain it in a examble:

A1=10
B1=20
C1=2000
D1=20
E1=C1-A1-B1-C1
E1 will shows value 1950

Then Copy E1 all the column down to E10
There are not values in cells below A1, B1, C1, and D1.

Cells E2~E10 should show value 0

However, they show 1950, the same value as E1.

ANyone have this problem before?
