The order of the block and element names should follow the hierarchy of the structure, from top to bottom. The Additional input parameter is not needed in this case, as it is already included in the Send JSON Path.

the calculation procedure version that would execute on 2/15/2020 at 12:00 PM is the one that has the start date time and end date time that include that date and time, and also has the highest priority among the enabled versions.

/2020 12:00 AM, an end date time of 4/1/2020 12:00 AM, a priority of 1, and is enabled. The other versions either have a different start or end date time, a lower priority, or are not enabled.
