In using absolutes the entire equation will not change. You can use the fill
feature to fill down, but you will have to go back and change the values.
Sorry, don't know a short cut for that.

Take the $ out of the equations. $ = absolutes, which tells excell that
those particular values do not change.

Hi,

I have a formula that sums the range

Cell B1 = Sum(A1:$A$100)
and this is copied down to cell B100,
so Cell B33 = Sum(A33:$A$100)

But I want the sum range to change, based on the value in cell C1.

If C1 = 100, then the sum range will = Sum(A1:$A$100),
Cell B33 = Sum(A33:$A$100)

If Cell C1 = 300, then the sum range will = Sum(A1:$A$300)
Cell B33 = Sum(A33:$A$300)

I tried using indirect but I could not figure it out.

Thanks for your help


That does not work because the last reference A300 must stay constant, and
A1 is the cell that changes
