    Problems Accessing Global Array

    I'm having problems accessing a global array variable from within a
    function. I have something like this:

    ------------------------------------
    var detail = new Array( 20 );
    detail[ 0 ] = "hello";

    function ShowDetail( ) {
    top.frames[2].document.clear ();
    top.frames[2].document.write ("<html><body>" );

    top.frames[2].document.write ( detail[ 0 ] );

    top.frames[2].document.write ("</body></html>");
    top.frames[2].document.close ();
    }
    ------------------------------------

    When I call ShowDetail(), I expect it to write "hello" in the frame, but
    instead it writes "undefined. " What am I doing wrong?

    Thanks,

    Greg.

      Nevermind. I made a stupid mistake, which is actually not in the code I
      posted.
