How to use the value from the Cascading field to trigger a action in a automation Rule?

[Deleted user]

I want to create a automation rule that should  assign an issue to a particular user based on the value from the child cascading field.

e.g 

Name of the Cascading List: Affected Service

Parent Values are: LIST 1 and LIST2 
Child values for LIST 1 : A,B,C 
Child values for LIST 2: E,F,G

IF LIST1 is selected and either A or B is selected for Child Value , then issue should be assigned to Reporter 1. IF C is selected then issue should be assigned to Reporter.


I am not able to find the created cascading field in the "Field" in "Field issue Condition" block used in automation rule.
