Actually, the line number in the error is one line off.  There's a hidden
line at the top of the python script.  However, good sleuthing - thanks for
providing that detail.

The actual issue is on the line above:

  a = -cosd*dxt-sind*dyt

where it's trying to multiply the fields.

What grid are you trying this with?  Are you subsetting on level at all?
What fields are you putting in for the theta and vector?

I've tried with the 80km NAM using a full grid or a specific level
and couldn't get it to fail, but I'm sure I'm just not using the
right combination.
