patch not working as example

[cesarcesar]

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.

Remove:

 var scalingMethod = 'image'; // or crop

 

otherwise it seems to be valid code
