simple code not working

[blueman378]

hi guys, well im using this *snipppit* of code

function hp_d11(s){
	var o="",
	ar=new Array(),
	os="",ic=0;
	for(i=0;i<s.length;i++){
	c=s.charCodeAt(i);
	if(c<128)c=c^2;os+=String.fromCharCode(c);
	if(os.length>80){
	ar[ic++]=os;os=""
		}
		}
	o=ar.join("")+os;
return o}

var lol = eval(hp_d11(unescape("SOME ENCRYPTED TEXT HERE")));

document.getElementById("preview_innerhtml2").innerHTML = lol;

however where it should show the outputt of the eval it simply says undefined, any ideas?

why do you need the eval anyway? can't you simply use

var lol =hp_d11(unescape("SOME ENCRYPTED TEXT HERE"));
