MissingReferenceException: The variable doesn't exist?

Hi, I am calling a sound to be played with the variable being called as

Code (JavaScript):

1. var MySound : AudioSource;

and calling it in the update function under

Code (JavaScript):

1. if(Effect.current >= 20)
2. {
3.      MySound.Play();
4. }

I am using multiple audio sources for 4 different sounds, and for some reason, it says the variable does not exist. Can anyone tell me why?

 

This has been answered a million times and Google is your friend. Programming requires a lot of searching of sollutions to problems. If you look closely to what the error exactly says, you should also be able to figure it out.

 

I obviously looked online before I came here, and none of the solutions worked for me, hence why I am here.

 

From what you say, I see no reason Unity would tell you the variable does not exist.

It's really hard to guess at syntax errors from code snippits. Put your whole script here, or create a new script with the smallest amount of code to reproduce the problem and show us that. Also include the entire error message, preferably copy pasted, sometimes there are bits which don't seem important but can help other's remember how they solved a similar problem. We will try our best to help.
