Hi,
I have the following code which produces an error suggesting the use of a
indexed-repeat. Does anyone have any suggestion on how to use
indexed-repeat() to make this code work.
Thanks,
James

In general, you cannot use ${fieldname} to reference any field within a
repeat group.
E.g., ${segment_name} does not work.
This is confusing, because if you create a form with just one copy of the
repeat group, everything is fine.
The problem occurs when you add the 2nd copy of the repeat.
The ${segment_name} then expands into a vector of values from the first and
second repeat.
E.g., [ value_from_first_repeat, value_from_second_repeat ]
but all your formulas are expecting a value, and not a vector.
The solution is to use relative references ("../segment_name") and think
about XPath expressions.
