fish number fish weight sum3-4 sum 4-5
31457 3.5
45367 4.5
34289 3.5

sum 3-4 should return sum of the two rows with between 3 and 4 (230111)
and sum 4-5 shold return sum sum of the row with 4.5 (45367)

If your data is in the cells a4:b6 try something like the formula below

=SUMPRODUCT((B4:B6lt;5)*(B4:B6gt;4)*(A4:A6))

It is not clear if you require lt; and gt; or lt; and gt;= for your
parameters

If I understand correctly, you want to multiply the number of fish by the
wieght and categorise the total weight by individual fish weight. It's not
clear what you want to do with a fish weighing exactly 4, so I've assumed
3-4 includes 4.

I've assumed your data as posted occupies A14

In C2
=IF(AND(B2gt;3,B2lt;=4),A2*B2,0)
Copy down the column
In D2
=IF(AND(B2gt;4,B2lt;5),A2*B2,0)
Copy down the column
At the bottom of columns C amp; D, sum the cells above eg
In C101
=SUM(C2:C100)
In D101
=SUM(D2100)
