Cumulative Averages

[#1]

How do I get a value for the cumulative value of any given ratio? I am computing Manufacturing Profit Margin % = Manufacturing Profit / Total Sales. I am trying to write an expression that will sum compute the overall value by taking Manufacturing Profit 1 + Manufacturing Profit 2 +Manufacturing Profit 3 / Total Sales 1 + Total Sales 2 + Total Sales 3 = Cumulative Manufacturing Profit Margin % for periods 1-3.  Any help?

Check this out:

Script:

Table:

LOAD * Inline [

Month, Metric, Value

1, Metric 1, 23996

1, Metric 2, 6245

2, Metric 1, 47980

2, Metric 2, 12489

3, Metric 1, 33692

3, Metric 2, 22108

];

Expression1: =Sum({<Metric = {'Metric 1'}>}Value)

Expression2: =Sum({<Metric = {'Metric 2'}>}Value)

Expression3: =Sum({<Metric = {'Metric 2'}>}Value)/Sum({<Metric = {'Metric 1'}>}Value)

Does this help?

Still no luck, Im getting the following, when I want to display the following values. I'm importing the numerator and denominator separately, summing them each month, and dividing the cumulative sum each month to mark the YTD margin %.

0.260252
0.260296
0.65618
0.480691
1.482634
0.863829
2.405509
1.462208
2.981861
1.634095
3.671661
2.017935

Can you verify that is this what you are trying to do?

Thank you so much, I was so close. RangeSum(Above(Sum(), 0, RowNo())) was very helpful.
