Re: Error in gsn_code.ncl

Hi Vanesa,

This is an older bug that was fixed in 5.2.1 I think.

What's happening is you must be loading gsn_code.ncl twice, and there are three functions (I think) that we forgot to put an "undef" in front of so they are undefined.

The fix is to load gsn_code.ncl only once, or to edit this file and add:

undef("is_cairo_ps")

before:

function is_cairo_ps(wtype)

You may have to do this for a couple of other functions.
