Look at the OFFSET function

Something like

=SUM(OFFSET(A1,0,0,ROUNDUP(B1)))

Maybe

Ok..I've been trying to bang out a formula that will essentially do a sum
on
a variable range within a certain column--Column A. The range will be
determined by a value in another column--Column B. Example: If the value
in
cell B1 is between 1-2, the formula sums cells A1 and A2 and returns the
value to, say, cell C2. Any advice on how to set up this kind of variable
range (for lack of a better term) within a formula would be greatly
appreciated.
