Too many output argument

I was trying to minimize, ‖Ax-y‖_2+k‖x‖_2+‖W*x‖_1
Where,A and W are matrices.
I have done this by simply editing one of the examples given in CVX.
But,this display the message as “too many output arguments”. why?
pls reply

You haven’t supplied the code that is causing the error. How can you reasonably expect anyone to be able to help?

I have recognized the error. that was a typing mistake. thanks for reply
