regridding problem

Hi all,
This is my first time trying to regrid my data and I am having problems
using one of the example scripts (regrid_1.ncl). I am just trying to use
the script to learn how regridding works and I get an error early on
saying- fatal:(lat) is not a named dimension in variable (sst). I have
put a copy of my script below, if anyone has any advice or help I would
greatly appreciate it. Thanks
