Hello!

I'm doing a menu-screen for my game and I've
thought I'd do it by changing some colors in the
palette every time the player presses up or down.
It doesn't work. Every time I press up or down, it
crashes (it just quits the program with no explanations).

Here's the code, why doesn't it work?

// The getcolor-part:

set_palette(paletti);

get_color(224,blue);
 get_color(225,gray);

// And the routine to change the colors:

 y=1; // This is just to know which option is selected


e(!key[KEY_ESC]){  
      if(key[KEY_UP]){
           set_color(224+y,gray);  // 224 is the index of the first color
                                                    // I use in the options, Here I make the current color (224+y)
                                                    // gray so that it's not selected anymore
            y--; 
           set_color(224+y,blue);  // And after changing "y", we change the new color to blue
    }
    if(key[KEY_DOWN]){    // Same thing but going down
          set_color(224+y,gray);
          y++;
          set_color(224+y,blue);
    }
  }

Thanks for your help!
