Hi Zacchary! Try this:

// First you need to initialise an id variable called thing to nil.
id thing = nil;

// Next, the challenge asks you to initialise thing to an NSNumber 4 using literals (remember literals are declared using the @).
thing = @4;

// Finally, the challenge asks you to print the result, looking like "thing = 4".
NSLog (@"thing = %@", thing);

Hope this helps!

Thank you Rodrigo for answering so fast ! ;)
