Error: Object doesn't support this property or method

[jglover45]

I'm running the following javascript with no problem in FireFox:

var multiGallery = {
    init: function(options){
        this.overlay = new Element('div').setProperty('id','lbOverlay').injectInside(document.body).addEvent('click',this.close.bind(this));
        this.gallery = new Element('div').setProperty('id','gallery').injectInside(document.body);
        this.fx = {
            overlay: this.overlay.effect('opacity', {duration: 250}).hide()
        }
    },

In IE7 I get an error that says "Microsoft JScript runtime error: Object doesn't support this property or method" on each of the "this." statements.

Anyone have any issues with this and have a fix for it?

Thanks!

Are you using a library, e.g. jQuery?

Can you post the rest of the code (if not too much) or a link?
