How to reference fields in a looped group in calculator

Support
1

Hi,

I want to multiply some fields inside a repeatable (looped) group and give its answer in a fields which is also inside the same group.

for example, the repeatable group comprises of value1, value2 and product. I want to compute the result of value1 and value2 in the product field.

I have tried using this
calculate="/data/value1 * /data/value2"
in the binding of nodeset product, but its not working.

I want to repeat the group for several values, so I am using repeatable group.
How can I do that?

The reference should probably be /data/group/value1, not /data/value1.

Since this is a repeated group, you likely need to use a relative reference
(assuming the calculate field is within that group)

calculate="../value1 * ../value2"

Note that there are many limitations and problems with repeat groups, and
XLSForm's automatic use of a full path name when referencing a field (
${fieldname} expansion) generally does not work well within repeat groups.
