Hi All,

I have created a lightning component to display a public site from which we can get customers sigup.
I have created the Lightning component for this and able to view the page but, I am unable to fire the toast messages in this.
And also my Save button is not getting disabled after clicking on it. 
This is my code. Any help to solve this is appreciated. Thanks in advance.
Lightning component:
