Displaying the number of a repeat in a label

Hello everyone,

You can use a calculate type question and the position() operator to get the repeat number to use in a question label. See your updated form here: repeat_edited.xlsx (8.9 KB)

You might also pack all questions/elements inside the repeat in a group and reference the position in the begin_group label.

Thank you all for your help
