I cut and pasted your macro into a new empty file and added the one line
#debug concat("AAAAA: ",str(NextX(1,0),3,0),"\n")

I ran it with a couple of different parameters and it worked as expected 
(Black image, but a number returned to the message stream).

Are you sure you don't have an error in the main body of your code?
If you've got an open bracket out of place before any of the macro 
invocations, then that would explain the message.
