Advanced Objective-C stage 6 challenge

I'm having trouble with the second challenge:

Assign an NSNumber literal with a value of '4' to the variable 'thing'.

id thing = nil; (this is the first question's answer)

Any help would be appreciated.

NSNumber literals are written like this @1 or @2 or @3...

So, just assign @4 to thing on a new line and don't forget to end the line with ;.
