The Dink Network

Ok, maybe you couldn't help me with that script, but, how about this one??

At the end of the talk, Dink should walk away and be "teleported" to the next screen, but when he gets "teleported", Dink appears on a copy of the screen that he was before!!

Just like this.

|1|2|3|

Dink is at screen one, the script should transfer Dink to the screen 2, but he appears at the screen 1. So, I've moved Dink towards the screen 2, the map "moved" normally and I've appeared at screen 3!
This is very weird for me, so I've posted here 'cos I couldn't solve it by miself.
Here is the end of the script.

move(1, 8, 054, 1);

wait(500);
script_attach(1000);
//fadeout & cutscene?
fade_down();
//change maps and stuff ...
&player_map = 738;
sp_x(1, 570);
sp_y(1, 140);
load_screen();
fade_up();
kill_this_task();

}

Notes: "Screen 1" is # 737, so 738 is scrn 2, 739...
The screen 2 is completely different from screen 1, so I wasn't tranfering Dink to a copy of screen 1

This is it, I'm trying hard to make it until the end of the year, 'cos without DN I would be nothing.
Scripting is harder than I tough...
