The syntax is described briefly here:
https://opendatakit.org/help/form-design/binding/ :
indexed-repeat(field,group,index, subgroup,subidx, ssgrp,ssidx,...)
Writing ${field-name} assumes you are using XLSForm and writing the
expression in the XLS file that you are converting to your XML file.
So if you are using XLSForm, the syntax is
indexed-repeat(${fieldName},
${top-level-repeat-group-name}, index-within-top-level-repeat-group,
${1st-nested-repeat-group-name}, index-within-1st-nested-repeat-group,
${2nd-nested-repeat-group-name}, index-within-2nd-nested-repeat-group)
If you have more than 3 nested repeats, we don't have anything that
supports accessing a particular value within the most-nested repeat.
I am having a hard time reading your XML file, but it appears that
Hole_name is within at least two levels of repeat groups. The example I
gave earlier:
indexed-repeat(${Type_pr_l_vement},
${group_cm8ku88},1,${group_dt8qr50},4)
Is referencing the value of "Type_pr_l_vement" in the 4th repeat of
"group_dt8qr50" that occurs within the 1st repeat of "group_cm8ku88".
See the Gotchas ( https://opendatakit.org/help/form-design/workarounds/ )
for a note about using indexed-repeat() and avoiding failures.

You have a nested repeat group. If you are trying to access elements from
that, you would need to use the nested form of the indexed-repeat:
e.g.,
indexed-repeat(${Type_pr_l_vement},
${group_cm8ku88},1,${group_dt8qr50},4)

Hi
I have a form asking several times (repeat) for
(1 hole can have several run and it is possibe to have several holes)
Then I would like to have the list of holes (defined previously) to
appear in a next question :
Q: Choose the hole :
- H1
- H2 ...
I have attached the xls file produced by kobotoolbox.
In the section repeat group (group_si3mn63), I would like to have the
list of the name of Trou (group_oy8am21)
I have tried to put ${Nom_trou} (but no success)
Thanks for any hint
Karim
