Even though I've found another solution to create the summary, I just want to double check this:
I can use those in a calculation, but when putting directly in the label for a note they don't work. So would it be possible to use the instance function? I tried with a couple of variations, but all gave errors. For example instance('data')/plotinfo[position() = 1]/datagrp/plotname.
As for the workflow and the need of a summary, it's just to have a single page where you can see the information entered and can double check some of the information.
From Generate a PDF for saving/printing inside the form I found the way to create the final summary by creating part of the summary in each repeat and then join them after the repeat. In the new form I create a text summary to show in the note and a html summary to create the pdf, I will have to check if I can create a single summary that I can use in both the note and for the PDF.
Well, add me as a complainer, but because I will probably use only Collect, I'll be able to live with formatting it for Collect only. If I need to use Enketo I'll use a relevant to check if the deviceid starts with collect or not.
I didn't test on an older version of Central, I made this form last week to demo something for a friend and then tested with an account on Kobo, where it worked. When I tested on Central it gave me the error. I modified it using you suggestions, and now that part works on both Central and Kobo (but it seems Kobo Collect doesn't print pdfs yet).
