  You seem to have very complicated ways of performing nested loops.
What's wrong with the traditional way of doing nested loops? In other
words:

#declare Cnt = 0;
#declare X1 = -1.5;
#while(X1 <= 1.5)
  #declare Z1 = -1.5;
  #while(Z1 <= 1.5)

    ...

    #declare Z1 = Z1 + 1;
    #declare Cnt = Cnt + 1;
  #end
  #declare X1 = X1 + 1;
#end
