    null or not an object?

    This code is for a little menu to the left on one of my pages,
    this menu has 4 links which are images home,index,links and about.
    when the mouse is over the image it's supposed to swap the image
    for an efect but it has an error:
    menu[...] is null or not an object.

    Heres the link for home:
    PHP Code:
    <a href="javascript:;" OnMouseOver="menuselection('2','1');" OnMouseOut="menuselection('1','1');">
    <
    img src="menu/halloween/home-1.bmp" id="menu_1" border="0" alt="Home"></a
    And the script:
    PHP Code:
    menu=new Array()    
    menu[1][1]=new Image
    menu
    [1][1].src="menu/halloween/home-1.bmp" 
    menu[1][2]=new Image
    menu
    [1][2].src="menu/halloween/home-2.bmp"   
    menu[2][1]=new Image
    menu
    [2][1].src="menu/halloween/index-1.bmp" 
    menu[2][2]=new Image
    menu
    [2][2].src="menu/halloween/index-2.bmp"
    menu[3][1]=new Image
    menu
    [3][1].src="menu/halloween/links-1.bmp" 
    menu[3][2]=new Image
    menu
    [3][2].src="menu/halloween/links-2.bmp"
    menu[4][1]=new Image
    menu
    [4][1].src="menu/halloween/about-1.bmp" 
    menu[4][2]=new Image
    menu
    [4][2].src="menu/halloween/about-2.bmp"

    function menuselection(onoff,sel){
    document.getElementById('menu_'+sel+'').src =menu[sel][onoff].src;

    Parse the arguments as numbers instead of strings.
    Code:
    OnMouseOver="menuselection(2,1);" OnMouseOut="menuselection(1,1);

    You need to call each array element as a new array
    Code:
    var menu=new Array(); 
    menu[1] = new Array()
    menu[1][1]=new Image();
    menu[1][1].src="menu/halloween/home-1.bmp";
    menu[1][2]=new Image();
    menu[1][2].src="menu/halloween/home-2.bmp";

    This page is framed but instead of using normal frames im using a
    iframe in the center but i dont know how to change the frame from
    outside of it, ie click a link from outside of the iframe and that
    link opens in the iframe.

    you will need to use the 'target' attribute of the <a> elements.
    Code:
    <a href="page.htm" target="<iframe name here>">Some Page</a>
