How do I make idle animation idle back to false in the animator control

Okay . I have idle animation with a boolean call isIdle and it is set to true when the game starts. I want to keep it their . The problem I am having it’s not playing the die animation with a trigger parameter . I want to try something new. I have notice that when I click on the die animation the idle its the idle. Right now I want to set the die animation as a boolean. I have a pic here :

Never mind . I did this to get it to work :

 if (m_DeactivateOnDeath) {
                Scheduler.Schedule(m_DeactivateOnDeathDelay, Deactivate);

                         GetComponent<Enemyai>().enabled = false;
