Hello Team,
As per the topic, I am getting this error:
Attempting to select element 21 of a list with only 21 elements.
My calculation is in a repeat group:
selected-at(#form/case_ids, #form/sample_processing/save_sample_properties_select_all/zero_position)
#form/case_ids a list of case_ids
and #form/sample_processing/save_sample_properties_select_all/zero_position is position()
