Multiple Counts Specific to Person Across Multiple Dates

Do you mean variations of this in J2 copied down?

=SUMIF($B$2:$B$9,B2,C$2:C$9)

Or perhaps this?

=SUMIF($B$2:$B2,B2,C$2:C2)

your request is not clear. Are you wanting a sum of column C for each courier by each date but on a row by row level because you will likely have duplicates.
this in J2 =SUMIFS(C$2:C$9,$B$2:$B$9,$B2,$A$2:$A$9,$A2) and dragged right to K2.
this in L2 =SUMIFS(F$2:F$9,$B$2:$B$9,$B2,$A$2:$A$9,$A2) and dragged right to M2.
unless you wanted otherwise, results hand entered would help.

Next time, please manually mock up what you ant instead of providing a blank grid and leaving it to guesswork.

Glad Ali gave you what you needed. And thank you for the rep even though you couldn't use mine.
