Fixed it, silly me

the new code:

global_settings{ambient_light 1}
#include "colors.inc"
#include "textures.inc"
#include "transforms.inc"

#declare block=
union{
box{<0,0,0><0.15,0.25,0.15>}

difference{
cylinder{<0,0,0><0,0.04,0>0.06 translate<0.075,0.25,0.075>}
text{
ttf "arial.ttf",
"LEGO",0.45,0
rotate <0,90,-90> scale <0.025,0.025,0.025> translate<0.06,0.295,0.1> }
}

}


#macro legobrick(X,Z,col,xup,yup,lastX)

#declare icount=0;
#declare myblock=

union
  {
#while(icount<Z)
 #declare jcount=0;
  #while(jcount<X)
object {block pigment{col} translate<(jcount*0.15),0,icount*0.15>}
    #declare jcount=jcount+1;
  #end
  #declare icount=icount+1;
 #end
 }

object{myblock translate<lastX*0.15,yup*0.25,0>}

#end

#declare WallX=5;
#declare WallY=4;

#declare Wall =
 array[WallY][WallX]
 {
  {2,4,4,4,2},
  {4,2,4,4,0},
  {2,4,4,4,2},
  {4,4,4,4,0}
 }

 #declare R1 = seed(0);

#declare aicnt=0;
#while(aicnt<WallY)
 #declare ajcnt=0;
 #declare lx=Wall[0][0];
 #while(ajcnt<WallX)


legobrick(Wall[aicnt][ajcnt],2,pigment{rgb<rand(R1),rand(R1),rand(R1)>},ajcnt,aicnt,lx)
#declare lx=Wall[aicnt][ajcnt]+lx ;
  #declare ajcnt=ajcnt+1;
 #end
 #declare aicnt=aicnt+1;
#end

background {color rgb <0.500, 0.500, 1.000>}
