A question for Giovanni - hidden calculated fields - inconsistent operation of online vs mobile app

[Peter Macisaac]

Rani can you please pass on:

Giovani

A method I use to avoid getting this display error for hidden calculated fields is to include in the calculation a trigger to populate it only after a data field has had data entered.

eg.    If([height] or [weight]=‘’,’’,[height]/[weight]))

This forces the calculated field to have a null value until the form is opened and data entered and avoids the error.  This works well in online version of REDCAP

However on the mobile app - using this approach with does not work so I have to display all calculated fields even if this is not needed for the user.

It would help if calculated fields had an option to remain null until all data required is entered and this would work on both online and mobile versions.

Happy to discuss further
