[IDV #PAA-696617]: Error

JP,

Right off the bat, there are a few problems with this formula:

- var 'mr' is not defined anywhere as far as I can tell

- var 'w' is reassigned which is confusing; use a different variable name. And
  argument 'vv' does not seem to be used

- var 'd' is assigned but never used

I would suggest cleaning up these problems, and see where you get.

Best,

Unidata IDV Support
