Dear all,

the purpose is to do a subtract to two cells, which are in the same colume
but one is upper 5 to the other.

First I have a vlookup string, "=VLOOKUP(B2,sheet2!A:M,3,FALSE)". Suppose
that the result of this vlookup value is located in sheet2!C10, I want to get
other value which is sheet2!C5. Cause C10 is not stable, it is located by
this vlookup string, how can I get the value of C5?

P.S. the value of each colume is not continous.

If anyone can give some hints, many many thanks to you!
