Not in body of function?

func greeting( ) { let greet = “Hello" println (“greet") } greeting( )

Keep getting the error 'You shouldn’t call the println directly it needs to be in the body of the function'To me the println IS in the body of the function so why do I keep getting this error?

Hello John:

If you put greet in quotes, it will make it string and will not call the greet constant. 

func greeting( ) {
    let greet = "Hello"
    println(greet)
}

// Calling the function

greeting( )

Hope this helps
