I'm trying to a blub to a lamp.   I created an include file for the blub and
created a declare statement to shortened my code in the pov file.  I used
the object modifier.  Did I used the wrong modifier to add the add within
the union statement?  here's the code:

// Persistence of Vision Ray Tracer Scene Description File
// File: ?.pov
// Vers: 3.5
// Desc: Radiosity Scene Template
// Date: mm/dd/yy
// Auth: ?
//

#version 3.5;
// Standard pre-defined colors
//
#include "lightblub.inc"
#include "colors.inc"
#include "metals.inc"

#declare Blub = light_source {
  <0,2,0>
  color rgb <1,1,1>
  area_light x*1, y*1, 2, 2
  adaptive 1
  jitter
  looks_like {Lightblub}
}
#declare Radiosity=on;

global_settings {
  assumed_gamma 1.0
  //max_trace_level 25
  #if (Radiosity)
    radiosity {
      pretrace_start 0.08           // start pretrace at this size
      pretrace_end   0.04           // end pretrace at this size

      //always_sample off           // turn sampling in final trace off [on]
      //max_sample 1.0              // maximum brightness of samples
    }
  #end
}

#default {
  texture {
    pigment {rgb 1}
    #if (Radiosity)
      finish {
        ambient 0.0
        diffuse 0.6

    #else

Within the union, the object modifiers should be specified after the
objects.  Moving the texture to after the object{Blub...} eliminates the
error message.  See if that gives a desirable result.  I didn't have
"lightblub.inc" to include for a complete test.
