I have a form field, type text, name ‘Organization’. It is not set as ‘required’ by default. Most use cases, I want it optional.

Now I have one use case (in one RSVP template) where I want it required.
Docs say:
“For any shortcode, if you start with “#REQ_” instead of “#_”, the field becomes required and cannot be left empty or 0 upon registration”

So I am using #REQ_FIELD{Organization} in this template, to make it required.
The field correctly displays as ‘required’ on the page.
However when I submit the form, with some text in that field, I get the message that it is not filled out correctly:
“Please make sure all of the following required fields are filled out correctly: FIELDOrganization”

I can put one letter or many words in the field, same result.

Also, in the form field editing UI, the selection for ‘required’ setting says:
“Use this if the field is required to be filled out.
This overrides the use of “#REQ” when defining a field in a format.”

It is not clear to me what “This overrides the use of #REQ…” means. Clearly a setting of ‘no’ (not required) here does not override my use of #REQ in this case, since the field behaves as ‘required’.
Or is some conflict between the field’s default setting of ‘no’ and my use of #REQ what is causing the error when I use #REQ this way?

thanks,
John
