actionscript 3 - AS3: Issues with multiple save/load slots -

i'm trying take simple "game" , give 3 save/load slots. following separate tutorial can make work single save slot once try adding more, gives me following error message.

1046:type not found or not compile-time constant: save2.

1046:type not found or not compile-time constant: save3.

i new actionscript 3 i'm sure i'm being newbish have tried figure out quite time can't seem to. whole thing controlled buttons placed on scene. appreciate can get.

the code:

import flash.net.sharedobject;  var savedataobject:sharedobject; var currentscore:number = 0  init();  function init():void{  btnadd.addeventlistener(mouseevent.click, addscore);  btnsave1.addeventlistener(mouseevent.click, save1); btnsave1.addeventlistener(mouseevent.click, savedata);  btnsave2.addeventlistener(mouseevent.click, save2); btnsave2.addeventlistener(mouseevent.click, savedata);  btnsave3.addeventlistener(mouseevent.click, save3); btnsave3.addeventlistener(mouseevent.click, savedata);  btnload1.addeventlistener(mouseevent.click, save1); btnload1.addeventlistener(mouseevent.click, loaddata);  btnload2.addeventlistener(mouseevent.click, save2); btnload2.addeventlistener(mouseevent.click, loaddata);  btnload3.addeventlistener(mouseevent.click, save3); btnload3.addeventlistener(mouseevent.click, loaddata);  }  function save1(e:mouseevent):void{ savedataobject = sharedobject.getlocal("savefile1"); }  function save2(e:mouseevent):void{ savedataobject = sharedobject.getlocal("savefile2"); }  function save3(e:mouseevent):void{ savedataobject = sharedobject.getlocal("savefile3"); }  function addscore(e:mouseevent):void{ currentscore += 1; updatescoretext(); }  function savedata(e:mouseevent):void{ savedataobject.data.savedscore = currentscore; trace("data saved!"); savedataobject.flush(); trace(savedataobject.size); }  function loaddata(e:mouseevent):void{ currentscore = savedataobject.data.savedscore; updatescoretext(); trace("data loaded!"); }  function updatescoretext():void { txtscore.text = ("score: " + currentscore); trace("score text updated"); } 

i tried code , works charm...

anyways, i've made simpler version doesn't use many functions , events.
here pure as3 version of (just save test.as3 , use document class in flash), can copy content of test() method , paste in action frame.

package {     import flash.display.sprite;     import flash.events.mouseevent;     import flash.net.sharedobject;     import flash.text.textfield;      public class test extends sprite     {         public function test()         {             /***** start: faking buttons , field *****/             var txtscore:textfield = new textfield();             addchild(txtscore);              var btnadd:sprite = new sprite();              var btnsave1:sprite = new sprite();             var btnsave2:sprite = new sprite();             var btnsave3:sprite = new sprite();              var btnload1:sprite = new sprite();             var btnload2:sprite = new sprite();             var btnload3:sprite = new sprite();              var items:array = [btnadd, null, btnsave1, btnsave2, btnsave3, null, btnload1, btnload2, btnload3];              (var i:int = 0; < items.length; ++i)             {                 var item:sprite = items[i];                  if (item)                 {                     item.graphics.beginfill(math.random() * 0xffffff);                     item.graphics.drawrect(0, 0, 100, 25);                     item.graphics.endfill();                      item.x = 25;                     item.y = * 30 + 25;                      addchild(item);                 }             }             /***** end: faking buttons , field *****/              var savedataobject:sharedobject;             var currentscore:number = 0              btnadd.addeventlistener(mouseevent.click, addscore);              btnsave1.addeventlistener(mouseevent.click, save);             btnsave2.addeventlistener(mouseevent.click, save);             btnsave3.addeventlistener(mouseevent.click, save);              btnload1.addeventlistener(mouseevent.click, load);             btnload2.addeventlistener(mouseevent.click, load);             btnload3.addeventlistener(mouseevent.click, load);              function getlocal(target:object):string             {                 if (target == btnsave1 || target == btnload1)                 {                     return "savefile1";                 }                 else if (target == btnsave3 || target == btnload2)                 {                     return "savefile2";                 }                 else if (target == btnsave2 || target == btnload3)                 {                     return "savefile3";                 }             }              function save(e:mouseevent):void             {                 var local:string = getlocal(e.target);                 savedataobject = sharedobject.getlocal(local);                 savedataobject.data.savedscore = currentscore;                 trace("data saved!");                 savedataobject.flush();                 trace(savedataobject.size);             }              function load(e:mouseevent):void             {                 var local:string = getlocal(e.target);                 savedataobject = sharedobject.getlocal(local);                 currentscore = savedataobject.data.savedscore;                 updatescoretext();                 trace("data loaded!");             }              function addscore(e:mouseevent):void             {                 currentscore += 1;                 updatescoretext();             }              function updatescoretext():void             {                 txtscore.text = ("score: " + currentscore);                 trace("score text updated");             }         }     } }
