and you are trying to display a variable called "dz"? In your
earlier<br clear="none">
example you tried to display z? In both cases GrADS is telling you<br clear="none">
these are not variables... and they are not. You should, however,
be <br clear="none">
able to display any in the above list (and dimensions if you want).

Are you trying to run a script or define a variable?<br clear="none">
