How to find data on a another sheet dependent on cells, rows and columns

Hi,

I'm really not sure what this is called so sorry if the description and tags aren't very clear. But I'll try my best to explain.

I'm putting together a sheet that from a drop down list of months will go fetch data for that month in another sheet in the same workbook. But I have around 100 different rows for various measurements. Is there a 'generic' formula that will read the row name, look at month is listed on the drop down and return the value. Instead of doing individual SUMIF?

For example on the attached - on the Month column in cell C3 I want a formula that reads A3 'Problem', M2, 'Jan' (which would be a drop down) and then on sheet 2 return the value for Number of problems in Jan, in this case 3.0 and then if I changed the month to Feb it would then return in this example 0.5 in cell D3.

I hope this makes sense. I think basically I'm looking for a generic formula that saves me having to write individual formulas. The example is one of about 20 I need to do, hence the need for a time save?

Thank you,

In M3

=INDEX(Sheet2!$C$3:$P$10,MATCH(Sheet1!$A$3,Sheet2!$A$3:$A$10,0),MATCH(Sheet1!$M$2,Sheet2!$C$1:$P$1,0))
