Underwater effects error?

Post the script here - it's an error in line 23 of the UnderwaterEffects.js, but we need to see it to help you. All scripts in the Assets folder and subfolders must compile ok - even those you're not using.

var waterLevel : float; var uAudio : AudioClip; var aAudio : AudioClip;

var uColor = Color(1,1,1,1); var uDensity = .05;

var aColor = Color(1,1,1,1); var aDensity = .008;

var waterSurface : Renderer; var underwaterSurface : Renderer;

private var below = false; private var glow : GlowEffect; private var blur : BlurEffect;

function Awake() { if(!waterLevel) { water = FindObjectOfType(Water); if(water) waterLevel = water.gameObject; } aColor = RenderSettings.fogColor; aDensity = RenderSettings.fogDensity;

 glow = GetComponent(GlowEffect);
 blur = GetComponent(BlurEffect);
 if( !glow || !blur )
 {
     Debug.LogError("no right Glow/Blur assigned to camera!");
     enabled = false;
 }
 if( !waterSurface || !underwaterSurface )
 {
     Debug.LogError("assign water & underwater surfaces");
     enabled = false;
 }
 if( underwaterSurface != null )
     underwaterSurface.enabled = false; // initially underwater is disabled

}

function Update () { if (waterLevel < transform.position.y && below) { audio.clip = aAudio; audio.Play(); RenderSettings.fogDensity = aDensity; RenderSettings.fogColor = aColor;

     below = false;
     
     glow.enabled = !below; 
     blur.enabled = below; 
     waterSurface.enabled = true;
     underwaterSurface.enabled = false;
 }
 
 if (waterLevel > transform.position.y && !below)
 {
     audio.clip = uAudio;
     audio.Play();
     RenderSettings.fogDensity = uDensity;
     RenderSettings.fogColor = uColor;
     
     below = true;
     
     glow.enabled = !below; 
     blur.enabled = below;
     waterSurface.enabled = false;
     underwaterSurface.enabled = false;
 }

}

Thats my Underwatereffects.js. I barely understand this...

Line 23:

if(water) waterLevel = water.gameObject;

What's a water gameobject? I'm sorry, im new to this.
