Cocos2d Adding Menu to the Scene

Question

I have a scene called CongratsScene which is loaded something like this:

[[CCDirector sharedDirector] replaceScene:[CCFlipAngularTransition transitionWithDuration:0.8f scene:[CongratsScene scene]]];

For some reason I am not able to add the menu to the scene. Here is the code:

+(id) scene 
{
    CCScene *scene = [CCScene node]; 
    CongratsScene *layer = [CongratsScene node]; 

    CCSprite *background = [CCSprite spriteWithFile:@"congratsscene.png"];
    background.anchorPoint = CGPointMake(0,0); 
    [layer addChild:background];

    [scene addChild:layer]; 
    return scene; 
}

-(void) restartGame:(CCMenuItem *) item 
{

}

-(id)init 
{
    if( (self=[super init] ))

    {

        NSLog(@"init congrats fired!");

    // add the restart game button 
    CCMenuItemImage *restartMenuItem =[CCMenuItemImage itemFromNormalImage:@"restartbutton.png"
                                                           selectedImage: @"restartbutton.png"
                                                                  target:self
                                                                  selector:@selector(restartGame:)];
    CCMenu *menu = [CCMenu menuWithItems:restartMenuItem,nil];  
    menu.position = ccp(50,50);     


    [self addChild:menu]; 


    }

    return self; 
}

UPDATE 1:

In the output window I am getting:

Unable to access variable "restartMenuItem"

UPDATE 2:

I solved my problem by changing the name of the menuItem variable and now it is working again. Not sure what was the main reason!
