Unknown identifier when turning off SSAO through a JS script

Hello. In my project, I want to add an option to turn off SSAO (image effect) through a menu. Here is what I get:
Unknown identifier: ‘ScreenSpaceAmbientOcclusion’.
I’m completely sure that’s the name of the script. Here’s the code:

if(handlerObj.GetComponent(handler).selectedSs==0) {

The script is attached to the camera, and so is SSAO, so this should work, but it just says unknown identifier. It might have something to do with the fact that SSAO is a C# script while all my scripts are JS. Does someone have a clue what the problem could be?

So here’s how it should be:
if(handlen.GetComponent(handler).selectedSs==0) {
Now it works.
