Function not working inside even listener script

I found a great listener script that listens for the onResize method, but I'm trying to pass another function inside this function that will update the document.title object and display the window's width.  My problem is, I'm getting an undefined on my change() function.  Any ideas?
function change() {
		document.title = wWidth;
	}
	function attachEventHandler(element, eventToHandle, eventHandler) {
		if(element.attachEvent) {
			element.attachEvent(eventToHandle, eventHandler);
		} else if(element.addEventListener) {
			element.addEventListener(eventToHandle.replace("on", ""), eventHandler, false);
		} else {
			element[eventToHandle] = eventHandler;
	  	}
	}
	attachEventHandler(window, "onresize", function() {
		setTimeout("change()", 100);
		if(wWidth > 1000) {
			document.body.style.overflowY = "hidden";
		} else if(wWidth <= 1000) {
			document.body.style.overflowY = "scroll";
		}
	});

try with a dummy

var wWidth;

Open in new window


outside (and before) every function. This will make the variable "global"

Try this instead:

function change() {
	document.title = wWidth;
}

function attachEventHandler(element, eventToHandle, eventHandler) {
	if(element.attachEvent) {
		element.attachEvent(eventToHandle, eventHandler);
	} else if(element.addEventListener) {
		element.addEventListener(eventToHandle.replace("on", ""), eventHandler, false);
	} else {
		element[eventToHandle] = eventHandler;
  	}
}

attachEventHandler(window, "onresize", function() {
	window.wWidth = document.documentElement.clientWidth;
	setTimeout(change, 100);
	if(wWidth > 1000) {
		document.body.style.overflowY = "hidden";
	} else if(wWidth <= 1000) {
		document.body.style.overflowY = "scroll";
	}
});
