Your macro:
#macro Fence(Flength, Fheight, Fspace, Fdiam)
   #local i=0;
   #while(i< Flength/Fspace+1 )
      cylinder{ <0,0,0> <0,Fheight,0> Fdiam/2 }
      translate <i*Fspace, 0, 0>
     #local i=i+1;
   #end
#end

It loops over a cylinder and translate statement. You then call it in an 
object block...and get the expected result.
Since your translate statement is apparently intended to translate the 
cylinder, it should go in the cylinder block. And an object block can 
only contain one object, you need to put either the macro call or the 
loop itself in a union.

BTW, your "i" variable is poorly named. It is a good idea to always use 
at least one upper-case letter in a variable name, which will prevent 
conflicts with future keywords.
