Hello, I have created a quantitative variable “AGE”
and I wish to program a modality “999” for missing value
Hi @nohandoye and welcome to the community!
There are several ways to do that:
- You can add 999 as
Default Response
and write ahint
which says something like “Please leave 999 if you don’t know the age” - You can add a
calculate
type question and write anif-statement
which you can see in here: Advanced Calculate Question Type — KoboToolbox documentation
