Google Spreadsheet SUMIFs equivalent - google-sheets

Question

I need a SUMIFs equivelent in google spreadsheet. It only has SUMIF, no IFS.
here is my data:
# Salesman Term (Month) Amount
1 Bob 1 1,717.09
2 John 1 634.67
3 Bob 1 50.00
4 Bob 1 1,336.66
5 Bob 1 0.00
6 Bob 1 55.00
7 Bob 300 23,803.97
8 Bob 300 24,483.91
9 Bob 300 20,010.03
10 Bob 300 41,191.62
11 Bob 300 40,493.14
12 Bob 300 10,014.01
13 John 1 100.00
13 John 100 100.00
I want to add everything that BOB sold that the term is equal to or less then 100. I also want to SUM everything that bob sold that the term is greater then 100. Same for John.

Answer 1

You need to use the FILTER function combined with the SUMfunction. In your example with Bob, your function would be like (assuming your data columns is from A to C):
=SUM(FILTER(C:C;A:A="Bob";B:B<=100))

Answer 2

The new Google Spreadsheet, now has the SUMIFS function available.
You can use the following formula:
=SUMIFS(F1:F14,D1:D14, "=Bob",F1:F14, ">=100",E1:E14, "<100")
If you want to perform the calculation for John as well, I can recommend the following:
=QUERY(D1:F14, "SELECT D, SUM(F) WHERE E<100 AND F>=100 GROUP BY D LABEL D 'Who', SUM(F) 'Total'")
See example file I created: SUMIFS on DATA
