Sum() inside the same repeat

Hi Friends,

Suppose, I have a repeat group and under that, I want to ask how much cubic feet is for a particular tree within a community. Repeat for tree can go with any number of times. My intention is to get the sum() of cubic feet of 3 or 4 (suppose) trees just, however tree repeat can go further to any number. Is this possible to achieve in xlsform? Again, I may be wanting to sum() after another 3 or 4 interval of repeat number.

Looking forward to any ideas from ODK friend.
Kind regards,
Raj Pravat

Hi @Raj_Pravat

so as I understand you want do display something like a live calculation of all the previous answers in a repeatable group? For example if you have a repeatable group with an integer question and you add three groups:

answer: 5
result: 5

answer: 3
result: 8

answer: 7
result: 15

etc.? am I right?

Hi @Grzesiek2010,

Yes, exactly, your are right. Hope to get a solution help seriously.

You can still use sum() function which needs to be added outside of the group but it's possible to refer to that value.
