Hi all, I have a cashflow spreadsheet with Income and Expenses shown over a 25 year period. It is a simple sheet with income category and growth assumptions and a simple formula like =F2*(1*G2), copied across several columns. If I wish to add one off expenses or incomes in future years, I would then have to add an amount in the relevant column and potentially add a comment. What I would prefer to do is to have a separate sheet with a list of potential one off expenses, dates and values e.g. Trip to Peru, 2017, £5000. Of that information the value of £5000 would be added to the year 2017 under holidays in the first sheet. If then we wanted to put another holiday in that period it would add that value to in that year. Is there a way we can do this elegantly??
