The Dink Network

Got a problem again... I want a sprite to be created on the &current_sprite's sp_x and sp_y. But it doesn't appear on the &current_sprite but up in the left corner... Why?

Here's a part of the script by the way:

&duck_x = sp_x(&current_sprite, -1);
&duck_y = sp_y(&current_sprite, -1);
int &bombzor = create_sprite(&duck_x, &duck_y, 0, xxx, x);
sp_script(&bombzor, "dam-duck");
