Now a weirdest thing happened. I tried it when &story was still 22.
But now I am playing it and &story is over 23 and the fence appears again but it doesn't block me anymore and I can walkthrough it now.

I changed the script in this one;
void main (void)
{
if (&story <= 23)
{
sp_touch_damage(&current_sprite, -1);
sp_nodraw(&current_sprite, 1);

}
}

void touch (void)
{
say("I am not ready yet.", 1);
move_stop(1, 2, 180, 1);
}

Why does the fence appears again? It works fine but the fence must be invisible.
