dear exceltips,

The cell K2 = sum( I2*AS2)
in which
i2= 20871
AS2 =0.077.
So, the correct result should be K2= 1607.067.
Why it calculates to the cell of K2 result return now is
1598.588 - it is wrong answer.

For details, pls see the wrapwrepusage.zip file


It is a big different.
Pls instruct !
thanks
gary
