    Javascript Not Working on Apple Browsers

    Hi There

    My friend has asked me to take a look at his website. Javascript is not working on apple browsers, and its quite fundamental to the page.

    The trouble is, I do not know javascript and don't really know where to start.

    Would anyone be able to take a look and see if there is a quick diagnosis? I'm hoping that the problem could be quite simple!

    Please take a look http://tinyurl.com/7od28fv

    Here is the code in question

    Code JavaScript:
    var fadeimages=new Array()
    //SET IMAGE PATHS. Extend or contract array as needed
    fadeimages[0]=["images/home1.jpg"] //plain image syntax
    fadeimages[1]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[2]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[3]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[4]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[5]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[6]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[7]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[8]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[9]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[10]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[11]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[12]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[13]=["images/home2.jpg"] //image with link and target syntax
    fadeimages[14]=["images/home2.jpg"] //image with link and target syntax
     
    var fadeimages2=new Array()
    //SET IMAGE PATHS. Extend or contract array as needed
    fadeimages2[0]=["images/front1.jpg"] //plain image syntax
    fadeimages2[1]=["images/front2.jpg"] //image with link and target syntax
    fadeimages2[2]=["images/front3.jpg"] //image with link and target syntax
    fadeimages2[3]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[4]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[5]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[6]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[7]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[8]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[9]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[10]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[11]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[12]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[13]=["images/front4.jpg"] //image with link and target syntax
    fadeimages2[14]=["images/front4.jpg"] //image with link and target syntax

    }
    this.rotateimage()
    }

    and the images at the top appeared to be called by the following script in the body of the page

    Code JavaScript:
    <script type="text/javascript">
    //new fadeshow(IMAGES_ARRAY_NAME, slideshow_width, slideshow_height, borderwidth, delay, pause (0=no, 1=yes), optionalRandomOrder)
    new fadeshow(fadeimages, 985, 263, 0, 3000, 1)
    </script>

    Thank you in advance for assistance of any kind, I am up the creek without a paddle!

    Thanks

    Daniel

    Does not work in Chrome either.

    Gives a javascript error on

    crossobj.style.KhtmlOpacity=obj.degree/100

    The variable obj is not defined.

    The comment says it is version 1.5. Dynamic drive has a version 2.4 so it is probably best to start by upgrading
