Hello everyone, I have this case:

Field 1: Expiration Date (Type: Date)
Field 2: Previous days (Type: Number)
Field 3: Date Notice (Type: Date)
The user of field 1 provides a date, field 2 indicates the number of days before warning and based on this must be the value in field 3. (Field 1-Field2)

For example:
Field 1 is 20.04.2019.
Field 2 is 15
The field should be 05.04.2019

I would prefer this to be done on Forms, is it possible?.

Tranks a lot.
