Sum two integer field values

[QK]

Hello, 

I want to know if it is possible to sum up two field values.  For example, when N1 and N2 are filled,  the sum (N1 + N2) should be shown in N3.

Hello,

You would need a plugin for it. For example, you could use the Power Script add-on:

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

#{N3} = #{N1} + #{N2};

You can find more info about post functions here:

Thank you!   Is it possible in scriptrunner add-on?
