display the field if the value is not empty

GregoireCatineau

Hi,

I would like to display the field value if a value exist in this; on the same line...

type	name	label	hint	relevant
text	C22_ZTI		Zone Touristique Internationale	${C22_ZTI}!=''

 

I recieve this error message: 

b'ODK Validate Errors:\n>> Something broke the parser. See above for a hint.\nDependency cycles amongst the xpath expressions in relevant/calculate\n\nResult: Invalid'

Your issue is that you are referencing the value of the field in its own relevant expression, creating a loop. You need to base the relevant expression off a different field's value.
