The Dink Network

I hate it when the most simple scripts don't work. I'm trying to let Dink crawl through a hole like in the original Dink, as a matter of fact I practically copied this script from the original Dink. Why doesn't it work?

void main( void )
{
preload_seq(452);
}

void touch( void )
{
say("yes!", 1);
freeze(1);
sp_x(1, 346);
sp_y(1, 343);
sp_seq(1, 452);
sp_frame(1, 1);
sp_nocontrol(1, 1);
//dink can't move until anim is done!
sp_touch_damage(&current_sprite, 0);
sp_brain(1, 0);
wait(2000);
sp_brain(1, 1);
&player_map = 566;
sp_x(1, 315);
sp_y(1, 350);
load_screen(566);
draw_screen();
}

The "yes!" is for testing purposes, but Dink never says yes, nor does he crawl in the hole and teleport. What's wrong?
