oops, I am sorry, I meant to, but must have forgotten to paste the 
code...  Its working now...  sorta, here is the code if you are curious

I adjusted the max gradient and the threshold






camera
{
   location <2,2,-13>
   look_at  <0 ,0,0>
}
light_source
{
   <2,0,-5>
   color rgb 3
}
#declare myfunct= function(x,y,z,r){x*x+y*y+z*z-r*r};
isosurface
{
// function{myfunct(x,y,z,2)}
   function{(x*x)+(y*y)+(z*z)-(2.5*2.5)}
   threshold 2
   max_gradient 2
   contained_by {sphere {0,3}}
   pigment
   {
      color rgb <.8,.2,.8>
   }
}
plane
{
   y,-4
   pigment
   {
      color rgb .85
   }
   
}
