Hi DHIS community, Could someone advise me on how to distinguish between a zero and a null in a validation rule?
Basically, I want the validation to pass if a data value is not blank. It should pass even if the value is zero, as long as it's is filled in. "Zero is significant" is on. I tried d2:hasValue from the program rules, but got the "expression is not well-formed" message. Is there a different way to check this in validation rules? Thanks!
