The Dink Network

I have recently been trying to create my own Dmod but i am haveing trouble changing the vision, here is a copy of the script i'm using.

void main(void)
{
if(&story == 1)
{
&vision = 1;
move_stop(1, 2, 135, 1);
wait(200);
say_stop("blahblahblahblah", 1);
wait(200);
move_stop(1, 6, 509, 1);
wait(200);
say_stop("blahblahblahblah", 1);
sp_dir(1, 2);
wait(200);
unfreeze(1);
&story = 2;
}
}
