Automatically Get the calculated value in the custom field

[Lavanya B]

I created a new custom field. For ex: Field A

Already Field B is present in the create screen.

I need a calculated value i.e [Field A = Field B - 30%] to be automatically displayed in the new created custom field.

Hello,

You would need an add-on for it. For example, you could use the Power Scripts add-on:

You could create a post function with a code like this:

#{Field A} = #{Field B} - #{Field B} * 0.3
