Need scripted custom fields= to calculate sum up based on other field values

[Nagaraju]

I need Scripted field will sum up the score values and show it in the ticket on.

For example, I have 3 fields called

1. Sensitive = Values are Yes, No, Others (Score Values Yes=5, No=0)
2. Automated = Values Yes, No (Score Values Yes=10, No=5)
3. Region = Values are USA, UK, Africa, Chinna, Brazil (Score Values USA=8, UK=7, Africa=5, Chinna=6, Brazil=7)

I need a script field that calculate values numbers.

ex Sensitive=Yes, Automated=No, Region=USA Total values 5+5+8 = 10 should be on scripted field.

There's nothing resembling most concepts of "sub-projects" in Jira.  It doesn't make a lot of sense in the context of Jira.

The standard answer when someone mentions "sub-projects" is "use the components field to break up your project into sections"
