To be honest, I don't want to try and debug your program remotely: please
try and reduce your problem to something simple (and preferably illustrate
it with a program that doesn't have lots of 'magic numbers' in it).
Please cut and paste rather than than typing it in by hand, too.

Can you get a simple surface plot with the couple of lines of code I
posted two days ago?
