Enumerate cosecutive numbers

What is the problem? Please be detailed.
I want to list a field in a form with consecutive numbers within repeated groups of questions. For example, I have 25 stations and I need a form to take station 1 and the next station automatically take number 2 in a group. How I do this?

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.

Within a repeat group you can use the position(..) function (eg in a suitable calculation) to get the index of that repeat group, starting at 1. Try something like this within your repeat group:

index: calculate = "position(..)"
station: "This is station ${index}"
