Hi Eduardo, thanks a lot...
I also fixed some logic, it seems I can't use List_Delete with Loop's current row number.
Now it does List_Append instead if fields was used (not removed).
Everything's now good except JSON_Objectify still return a key/value JSON instead of expected Object JSON.
It seems JSON_Listify return key/value pair instead of name/value pair, while JSON_Objectify expect name/value pair?
Any thought?
