[gradsusr] Cannot contour grid - all undefined values

I'm not an expert on reading wgrib output, but I don't see anything that
immediately strikes me as wrong. I do find it odd that there is one output
for each of the five levels, though. Doesn't mean anything is wrong,
though. The only help I can further offer is to make sure you used gribmap
on the control file to create the index file. I would think Grads would
give you a more obvious error if the index file didn't exist, but maybe it
didn't. If that doesn't solve your problem, someone else wiser than me
will have to step in and help you.
Good luck.
Jeff
