Hi, thanks. I am seeing your two bump_map declarations, but not that you
specified the bump image. I tried to incorporate everything, but still
fail (now with error message):

 normal
 {
  gradient y
  normal_map
  {
   [ 0.175 PositiveBump ]
   [ 0.175 NegativeBump ]
  }
  bump_map { png "H:\My Documents\My Pictures\POV-Ray\Space - Launcher -
Balloon - Type 001 - Moon Runnings - Balloon BumpMap.png" map_type 1
once bump_size 150.0 }
  scale < 1.0, 1.5*MyRadius, 1.0 >
 }
