sorry...its the wed tutorial. Its in the Basic scripts first level section.

these are the lines with the errors in them.
if(my._move_min_z__003 >= 0) { move_min_z = min(0.99,my._move_min_z__003); }
and
move_min_z = 0;

on line 230 though it has
define _move_min_z__003,SKILL9; // used to set the move_min_z durring moves

Is this where the problem is?
