Cascade select with selected() not working

[Webex]

Hi,

I want to use cascading select function with selected(${xx},'xx'). I created a survey
Trial_errors.xlsx (12.9 KB) and checked it with https://getodk.org/xlsform/. However, the cascade select is not functioning, even after reading Adding Cascading Select Questions — KoboToolbox documentation. Could anyone enlighten me what I am doing wrong?

Thanks!

In multiple choices names, blanks are invalid. It is also recommended not to use blanks for select_one choices. See

• https://community.kobotoolbox.org/t/form-preview-error-while-cascading-the-options-to-the-previous-question/34228/4
• https://xlsform.org/en/#choice-names.

You can find a lot of examples with the search function of the forum, e.g. How to create a multi layer cascading select question? - #19 by Kal_Lam.

Hint: When you reference select_one, you can just reference directly as ${select_oneVariable}. selected(…) is only needed for select_multiple.
