=SUMPRODUCT(--(b2:B200>=--"2006-08-01"),--(B2:B200<=--"2006-08-03"),--(B2:B200<=--"2006-08-01"),--(c2:c200="apple"),a2:a200)
it works but it but when I want the sum for only one day it does not
work.
I am a little confused, what do the 2nd and 3rd term do? if b2:b200 <
2006-08-01 it will also have to be less than 2006-08-03
Also as it is written it will only select values in column B if they
equal 2006-08-01. If any times are also included for a given day, it
will not be selected, would would have to add 1 to the day you were
interssted in to account for this.
or am I missing something

You don't need to test <= twice.
This works for me with just a single day
