Attached file 151031 Comparisons.xlsx has three sheets with Actual, Forecast and Budget numbers for various months.

End user wants the ability to select and compare any two periods by selecting the relevant months and categories.

I have created the "choice" range in Col H of the Comparisons sheet, but can't see what formula will "find" the relevant column on the correct sheet from the list?

Any suggestions received gratefully, as ever
