问题
I have 3 columns with values filled in already in my metasheet. A combination of values in column A and column B makes the selection unique. I need to pull/return the value in column C for the values selected in columns A & B. for example: In sheet 1, I have the following data:
country Month weather
1 USA Jan winter
2 USA Feb fall
3 USA May summer
4 China Jan summer
5 China Feb spring
6 China May fall
7 India Jan fall
8 India Feb summer
9 India May Rain
Now, say for a random row 25, I have A25 as a dropdown list with value selected ="India" and B25 as a dropdown list with value selected="Feb", in which case I would want C25 to have a dropdown list with the value in it being "Summer".
I tried this formula:
=VLOOKUP(B25, OFFSET(B$1:C$9, MATCH(A25,A$1:A$9,0)-1, 0, 2, 2), 2, 0)
But this one gives me an error: "The list source must be a delimited list, or a reference to a single row or column". I did refer to this solution. But I get the above mentioned error as the data validation for C25 is a list.
Any suggestions/ideas on this would be helpful! Thank you!

If your sheet is set-up like this:
You can use:
=INDEX(C2:C10,INDEX(MATCH(1,(A2:A10=E2)*(B2:B10=F2),0),0))

You will need to make a second sheet with a matrix like following -
Here you will define all the weathers for country and month pair. I have used the default name i.e. Sheet2 and filled the values that were available from your data. You will lookup the values from this for filling on Sheet1. Sheet1 will be like this -
=VLOOKUP(B2,Sheet2!$A$1:$D$13, MATCH(A2, Sheet2!$A$1:$D$1, 0), FALSE)
Here B2 is the month value, A2 is the country value. Sheet2!$A$1:$D$13 is the range for VLOOKUP and Sheet2!$A$1:$D$1 is the range for MATCH. VLOOKUP will match the month, MATCH will match the country and get the column index.
