Make slider disappear when reach max value

Hello, I am new to Unity. I want to make the slider disappear when the max value is reached. How do I do it?
I done a script but it is not doing anything. (The max value for the slider is set 5)

public Slider patientslider;
public float value;
public bool IsON;


void Start()
{
IsON = true;
patientslider.enabled = true;
}
public void Changes()
{
if( value == 5)
{
IsON = false;
patientslider.enabled = false;
}
}

 

Ok, found my problem.
