Question

Basically I have a table like this:

Week   |   Value
1      |      2
2      |      3
2      |     -1
2      |      1
2      |      1
3      |      4
3      |      2    
6      |      4
7      |      1

I need a chart to show the sum of the values for each week only if the value is greater than 0.
so

• week 1 –> 2
• week 2 –> 5
• week 3 –> 6
• week 6 –> 4
• week 7 –> 1

Anyone have any idea how to do this?

Answer 1

If you have Excel 2007/2010, you can use the newer function SUMIFS as below:
=SUMIFS(Week_Values,Week_Numbers,This_Week2,Week_Values,”>0″)
