Multiple choice on repeat groupe answer

What is the problem? Please be detailed.
We scan a barcode, and calculate is use with Pulldata to get back the real name of the item

I have a repeat groupe in with this operation

I need at the end to allow to make a multiple_choice between all the scan item.
How could I get the list of the name of item in my multiple_select last question ?

I think Xpath could be useful but I didn't catch how to enter Xpath into multiple_choice list with depend on choice sheet and not survey sheet

What ODK tool and version are you using? And on what device and operating system version?
ODK1 v1.17

Hi @Fabienne35

based on this answer Ranking previously collected list of names

  1. Download the form I prepared: barcodes.xlsx (6.2 KB)

  2. Convert it to xml using http://opendatakit.org/xlsform/

  3. Add:

	 <itemset nodeset="/barcodes/group">
	     <value ref="c1"/>
	     <label ref="code"/>
	 </itemset>

instead of:

 <item>
    <label>A</label>
    <value>a</value>
 </item>

in line 38 under

<label>Select barcodes</label>

Here is the result: barcodes.xml (1.6 KB)
