Use of jr:choice-name in xlsform

Support
1

Hi Team, I wanted to refer to a label using jr:choice-name. Can any team
member give me a step by step way of using it to refer to previously
entered choice label in xlsform.

I have tried and i keep getting this error message: Error: "... There has
been a problem trying to replace ${livestockactivity_list} with the XPath
to the survey element named 'livestockactivity_list'. There is no survey
element with this name..."

Thanks.

Collins,

jr:choice-name cannot have a blank value for its first argument. See
https://groups.google.com/d/msg/opendatakit/A8GBWt8cYvo/4r-NsLXAbZcJ
for the details.

Workaround is something like this:
if(string-length(${livestockactivity_list}) !=
0,jr:choice-name(${livestockactivity_list},'${livestockactivity_list}'),'(unspecified
livestockactivity)')

Dear @yanokwa, I'm trying to access the google group you mentioned in this post, but it seems unavailable. Is the group or the post still active?
I want to learn more on jr:choice-name, can you redirect me to relevant materials?
thanks, Lavinia

Hi @Lavinia_Plataroti, you can use CTRL + "F" to find "jr:choice-name" on this page of the documentation: https://docs.getodk.org/form-operators-functions/ - it's in the section on selected()

Hi there!
I read the docs but have another question: in my form, I first have a select_one question and then a begin group, wherein I included a jr:choice-name to refer to the select_one question outside of the group.
Is this funcionality supported? what could be a workaround?
I tried the path described in the docs, having the select_one questiton within the begin group and used the jr functon worked perfectly.
Thanks!

Is your group a repeat group? If yes, and you want to reference a question in the repeat group from outside of the group then you will need to know which number of the repeat you want. See: https://docs.getodk.org/form-repeats/#referencing-repeated-questions-from-outside-the-repeat

If it's a regular group (not a repeat), you shouldn't need to do anything special. If you are having issues please attach the XLSForm sample here to help people troubleshoot.
