[gradsusr] Help with gs scripts

[Jeff Duda]

It would help for you to show the script code you're using.

Without knowing the code, things to consider:
-Do those dimension ranges fit within the bounds of your data?
-Did you select LINEAR or VALUES for the steps of XDEF and YDEF?
-Did you select actual numerical values when setting lat/lon?
