Thanks for this info.  I've modified the formula to call a new Jython
procedure:

def combineRGB(red, green, blue):
  from ucar.unidata.data.grid.GridUtil import *
  red=setParamType(red,makeRealType("redimage"), 0)
  green=setParamType(green,makeRealType("greenimage"), 0)
  blue=setParamType(blue,makeRealType("blueimage"), 0)
  return DerivedGridFactory.combineGrids([red,green,blue],1)

instead of combineFields().  This will be in tomorrow's (8/30) build.

BTW, Jeff put in a fix for the problem you encountered with the 
support form.  If the message is not sent successfully, the form
will be displayed and your message will still be there.  If nothing
else, you can cut and paste the text to another app so you won't lose it.
We're not sure what went wrong, but this will at least keep you from
losing all your work.
