TRIGGER is preventing updates on fields

I have a table usersdev that contains my users information. It has 73 fields.

I want to create a trigger so that when a certain field named active_indicator is updated I insert  information into  a table named  audit_users.

I have successfully created that trigger See code below. But for the trigger I am only concerned when the  active_indicator is updated.

The problem is that when any of the other fields is updated the update doesn't save.

How do I set the trigger so that all off the fields in the usersdev  table can be updated  -not just the active_indicator field?

Its almost like I need to disable the trigger if the active_indicator field wasn't being updated.

This code right below works to save the active_indicator change information to an audit_users table.

But again only the active_indicator keeps the updated information

USE [mydatabase]

GO

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

ALTER TRIGGER  [myTriggerUPDATE2]

ON  [usersdev]

INSTEAD OF UPDATE

AS

DECLARE @iD84_2 int, @newactive_indicator int,@oldactive_indicator int

BEGIN

--set local variables

SET @iD84_2 = (SELECT ID FROM inserted)

SET @newactive_indicator = (SELECT active_indicator FROM inserted)

SET @oldactive_indicator = (SELECT active_indicator FROM deleted)

--UPDATE TABLE------------

UPDATE  [usersdev]

SET

active_indicator =@newactive_indicator  WHERE ID =@ID

--UPDATE AUDIT TABLE------------

INSERT audit_users (change_type, ID_changed,change_date,active_indicator)

VALUES('UPDATE', @iD84_2,CURRENT_TIMESTAMP,@newactive_indicator)

END
