patch not working as example

[empiresolutions]

I'm using the code found here. I am trying to insert some new code as per the instructions here. I have not been successful. The code i think I'm supposed to change is,

IE7.CSS.addFix(/background(-image)?\s*:\s*([^};]*)?url\(([^\)]+)\)([^;}]*)?/,function(a,b,c,d,f){d=cC(d);return bi.test(d)?"filter:"+i(bx,d,"crop")+";zoom:1;background"+(b||"")+":"+(c||"")+"none"+(f||""):a});

And its updated form should be like,

    IE7.CSS.addFix(/background(-image)?\s*:\s*([^};]*)?url\(([^\)]+)\)([^;}]*)?/,function(match, $1, $2, url, $4) {
        url = getString(url);

        // Hack for bg repeating support
        var repeatExp = new RegExp('repeat-[xy]','i');
        var scalingMethod = 'image'; // or crop
        var overflow = '';
        if (repeatExp.test($4)) {
            var scalingMethod = 'scale';
            overflow = 'overflow:hidden;';
        }

        return PNG.test(url) ? overflow + "filter:" + format(PNG_FILTER, url, scalingMethod) + ";zoom:1;background" + ($1||"") + ":" + ($2||"") + "none" + ($4||"") : match;

    });

Why is it not working? Thanks much.

If you check the status, it's new, not fixed.
