Working with nested if statements in the logic of the calculation column of CHT XLSForms

[raf]

Dear @michaelmafantiri
There is a bug in the implementation of enketo in Community Health Forum. Empty variables are evaluated to 0. This has been mentioned here:

ODK calculations: empty integer evaluate to 0

Migrating from ODK based platforms, I have realized that some calculations are differently handled in CHT. For instance an empty integer is evaluated to zero. If I have an integer, say height, and have a calculation later on that checks for instance if a child is smaller than a threshold: ${height}<90 This is evaluated to TRUE. In ODK it would be FALSE because ${height} is empty. See also here in ODK docs CHT equals an empty integer with 0 Could you point me to a reference, documentation …

Looking at your statement, you might have run into the same issue. Could you check this?
