I'm new to XLSForms and was wondering if any could help me. I am looking to
sum up a group of 20 repeating questions (there's no constraint on how many
times it could be repeated). I need it to sum up each time and then also
the sum total. In the example below, let's say that the group of 4
questions was repeated 3 times. I need the individual scores each time as
well as the total sum after it was repeated 3 times.

Q1. Does the scale hang on an immobile platform?
Yes - 2 points
No - 0 points

Q2. Is the scale calibrated to 0 including weight of harness?

Yes - 2 points
No - 0 points

Q3 Is heavy clothing removed before weight was taken?

Yes - 2 points
No - 0 points

*Q4. Is the infant seated correctly in the harness (one arm situated in
front of one harness strap and the other behind the opposite strap or in
some way balanced in the harness)?*Yes - 2 points
No - 0 points

A $total prompt with a calculate of $sum1+$sum2+$sum3 will give you
the sum inside the repeat. Then outside the repeat, sum($total) will
give you the sum of all the $totals.

Try it with a very small form and see how that goes.

For repeat groups, if $field1 is a numeric field in the repeat, you can
sum up all values entered into that field, across all repeat instances, by
using:
sum($field1)

Note, however, that the values in all choice lists are strings, not
numbers. So if you map "Yes" to 1, and "No" to 0, you are actually mapping
these to "1" and "0", not the numbers 1 and 0. i.e., sum($field1), where
$field1 is a select1 prompt, will fail because it is trying to sum over a
set of string values.

The solution is to have a calculated field immediately after the select1
prompt to store the value from that field as a number. I.e., a calculated
field "fieldN1" with a calculate expression of int(../field1) will
convert the value of field1 to an integer and store it in fieldN1. You can
then sum those fields using sum($fieldN1)
