I created a survey form in the desktop version of Survey123 Connect for the collection of insect information in an apple orchard. My client needs the insect count field left blank to indicate that they did not check a trap; a 0 in the field would mean they checked the trap and found no insects. If I set the field to required, a 0 is automatically populated in the field. How do I write a note using the 'relevant' field to ask them if they are sure the insect count field should be null? So far I have tried:
${Codling_Moth_Male}=NaN
${Codling_Moth_Male}==NaN
${Codling_Moth_Male}=null
${Codling_Moth_Male}=<NULL>
The first one, ${Codling_Moth_Male}=NaN, lets the form run properly but does not provide a note when the field is left blank.
