ImageEffects-toggling through code issues

I'm using Unity5 and i'm having issues with toggling ImageEffects of any sort through coding C# or JavaScript. i have even tried to write the most simplistic code of (Really rough example)

 function start ()
 {
     Camera.main.Getcomponent<SSAOEffect>().enable = false;
 }
 
 

Here is what i want to be able to do a toggle bool consisting of a on/off on(checked) = (example) SSAO ON off(unchecked) = SSAO off

any info you can give me will be better than 5hr of searching for a solution
