I need to require that either a barcode is read successfully OR a text field (with an alternative sample identifier) is completed.
Occasionally a barcode fails to read and there is provision for a text field on the same screen. I need to ensure that the text field is completed if the barcode is not recorded. So the 'required' parameter of the text field should be dependent on the presence of a value in the barcode field.
Any ideas how I might do that?
Thanks
Assuming you have ${barcode_question}, create a ${text_question} where
required is ${barcode_question} = '', then make sure both questions
are on different pages.

Thanks That works.
Why do you say the questions should be on different pages? I have them on
the same page and all seems to work as expected.

Steve,
Relevance doesn't work reliably when questions are on the same page.
