HTTPrequest doesn't work.

[Guest ikkuhqhp]

Hi, I got this code, but it doesn't seem to work. Can you please help? Thanks in advance!

<script language='javascript'>var nruser = 0 var users=new Array() var pagenr = 5users["0"]="user1" users["1"]="user2" users["2"]="user3"var xmlhttpfunction loadXMLDoc(){xmlhttp=null// code voor Mozilla, etc.if (window.XMLHttpRequest)  {  xmlhttp=new XMLHttpRequest()  }// code voor IEelse if (window.ActiveXObject)  {  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP")  }if (xmlhttp!=null)  {  xmlhttp.onreadystatechange=state_Change  xmlhttp.open("GET",'http://www.mysite.com/script.php?user='+users[nruser],true)  xmlhttp.send(null)  }else  {  alert("Your browser does not support XMLHTTP.")  }}function state_Change(){// als xmlhttp is "loaded"if (xmlhttp.readyState==4)  {  // als "OK"  if (xmlhttp.status==200)    {    alert('OK')	handlereturn()	}  else    {    alert("Problem retrieving XML data")    }  }}function handlereturn() { 	var input = http.responseText;  // this is wrong, it doesn't have access to that variable	var actie = input.substr(0, 1);	var tekst = input.substr(2, (input.length-2));	var output = '';	var geld = '';	if(actie == '*') 	{ 		if(tekst == '1') output = 'output 1';		if(tekst == '2') output = 'output 2';		if(tekst == '3') output = 'output 3';		if(tekst == '4') output = 'output 4';	} 	else if(actie == '+') 	{		output = 'return +';	} 	else if(actie == '-') 	{ 		geld = tekst;		output = 'return -';	}document.aanval_form.currentuser.value = users[nruser++];alert(output);}</script><form name="aanval_form"><input type="button" name="btnstart" value="Action!" onClick = "loadXMLDoc()"><input type="text" name="currentuser" id="currentuser" value='Slachtoffer' disabled="true"><br><br></form></body></HTML>

I did a quick check, and it fails at the handlereturn, the error was bad syntax. The variable doesn't have acces to that part of the script.so, problem solved!
