Hi, I'm writing an automation and I'm wanting to calculate the inverse of a numeric field in an issue.
For example, I have a custom numeric Issue field called bob with values from 1 -> 5
In my smart value I want to calculate "5 - <value of bob in the issue>"
I've tried doing the following, but I get `None` as the result. How should I do this?
5.minus(issue.impact)
