Problem:
REDCap “sees” zero differently for branching logic depending on its context:
- “0” or ‘0’
- 0 (an integer)
If you use want to branch logic based on the value of a field being zero, use quotes (single or double). Note: there is not a similar issue with unity (1).
Solution:
Replace
[var] = 0
with
[var] = ‘0’
