Use Case: Show a warning text if variables are not complete:
This module hides (with the action tag @HIDDEN) a variable [varX] (i.e., a descriptive field with a warning message) if any other variable tagged with the Action Tag @CHECKMISSING=varX is not empty.
Rationale: Instead of writing long branching logic for [varX], you can quickly tag (working with the data dictionary) the variables to take into consideration with the Action Tag @CHECKMISSING. For the end-user, it looks exactly like branching logic, but the side implementation might speed up the creation of forms.
Notes:
- The module look for the variables tagged with @CHECKMISSING which are available in the current page. By multi-page survey only variables in the current section will be "checked for missing values"
- @READONLY fields are considered as not-missing.
