My formula is:- =SUMIF('INPUT PAGE - FLYING TIMES'!$D$4:$D$23,D3,'INPUT
PAGE - FLYING TIMES'!$H$4:$J$23)

D4 to D23 is the part of my data which I'm looking for the answer in D3
(aeroplane type).
H4:J23 is where I looking for a numerical figures (flying time in minutes)

This is working well for the first column, (H) but is not taking note of the
2nd and 3rd column.

1/ Am I using the correct formula to pick data from 3 columns?
2/ If correct what should I do to the formula to make it work across all 3?
3/ If not, which one should I go for?
