Default Object expected error

Hi,
I have a script in my web page that runs a cross browser transition effect. It works perfectly in FF and well in IE as long as the option to display script errors is off. If script errors is on I get a "Object expected" error relating to this line:

var object = document.getElementById(id).style;

which is generating a null value. Being a perfectionist I would like to be able to remove the bug. The line of code belongs to this function which checks for the various browser transition functions:

//change the opacity for different browsers
function changeOpac(opacity, id) {

    var object = document.getElementById(id).style;
    object.opacity = (opacity / 95);
    object.MozOpacity = (opacity / 95);
    object.KhtmlOpacity = (opacity / 95);
    object.filter = "alpha(opacity=" + opacity + ")";
}

id refers to the image element the effect is applied to. opacity is a number defining the current level of opacity.
Any help would be much appreciated.
Thank you,
Steve

Hi hericles

It seems that no element with given "id" exists in your document. Send your entire code. It could be more helpful
