The cell K2 = sum( I2*AS2)
in which
I2= 20871 where the forumla here is I2=SUM(G2+H2)
AS2 =0.077 - where the forumla here is
=IF(ISERROR((AG2/(AG2+AJ2+AM2)*AD2)*A2*1.05/840/AF2), "",((AG2/(AG2+AJ2+AM2)*AD2)*A2*1.05/840/AF2))
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
