I am compiling a capital purchase forecast over five years togther with
forecast depreciation. The top of my spread sheet has months 1 through to 60.
I would like to calculate purchases in year 1, namely if it occurred between
months 1 and 12, similarly calculate purchases in year 2 ( occurring between
month 13 and 24) etc. Column A2:A20 has a list of proposed assets, column
B2:B20 their purchase cost and column C2:C20 the proposed month of
expenditure (1-60).

Can anyone help?
