Hi,

I already use the SUMIF function to calculate the total mileage for a
vehicle stored in columns A1:A50 if another column C1:C50 contains an 'x'.
However I now want to calculate the mileage if C1:C50 contains an 'x' and
column D1:D50 contains 'y'. I've looked at at various queries on this site
re
SUMIF with 2 variable but none seem to give an answer on how to nest these
two conditione into the 'CRITERIA' part of the function. Please can anyone
help?
