The only note I would add is that Indirect is a volatile function
(recalculate every time a calculation is run whether it needs to or not) so
it can slow XL down if you add hundreds (or thousands) of them.

I would like to be able to use a value in a cell as the numeric reference to
a row in another column, to which to sum values in that column.
Eg.
If A5 = 7, sum values in cells D3 to D7.
If A5 = 13, sum values in cells D3 to D13.
