Sumif by date?

[pshearer]

All;
I am trying to come up with a formula that will sum all the numbers in column I (“net”) per day, in column E.
For example, it sums all values on 1/19/17, 1/20/17, etc.
I’m sure there is a way, I seem to struggle with these “running” formulas. Sample attached.

Maybe I'm trying to skin the cat the wrong way; but I want a formula I can run to show total amount of weight picked up (column I) per day (column E).

Thanks ahead.

a pivot table would do that quickest

have you used pivot tables?

see attached
sheet1 - is that the result you are after?

edit - need to modify the sheet - too much to load here
i'll edit and attach later
