How can I set trigger to fire only after a change to cb field value

I have a cb auto action which is set to fire after the user updates their profile information. I would like to set a condition wherein the trigger only fires if a user changes the radio button on the field from “Yes” to “No” or from “No” to “Yes.”

In other words if they edit their profile and do not change the specified value then the trigger should not fire. What is the best solution for this?

You can use the following usage in any action.

Trigger: onAfterUserUpdate
Conditional: [var1_FIELD_NAME] Not Equal To [var3_FIELD_NAME]

var1 is the new user object and var3 is the old user object. This would compare the field to its old value to see if it changed. If it did your action will perform. This only fires on frontend profile edit, but you can add backend profile edit from the dropdown as needed. Replace FIELD_NAME with the actual name of the field to condition (e.g. [var1_name] and [var3_name]).
