[pyngl-talk] PyNGL script help

[Fearon, Dr. Matthew, Contractor, Code 7533]

Dear PyNGL users:

The following set of errors I am receiving are hard to diagnose. Any assistance would be appreciated. My script is attached and errors are below. I've a created a small script to plot COAMPS model output. The script works for one iteration, but then gives a series of errors on the second iteration. However, if I skip the first iteration, the second works... and so one. .

Thank you,
Matt
