Updating SharedObject Data Value in ActionScript - actionscript-3

Question

I want to update the value of _third.data["#ID"] in this code. What i want to do it to add something with _third.data["#ID"] when storing it in this.ID
What i want to do is:
this.ID = "myvalue" + _third.data["#ID"];
but in output i get myvalueundefined but if i remove "myvalue" from code thn it works fine and gives me the correct value please help me my knowledge of actionscript isn't that much i just learned some of it from internet.
Here is the coding:
public function main(_first:String, _second:Array, _third:SharedObject):Object{
this.ID = _third.data["#ID"];
};
What i want to do is:
public function main(_first:String, _second:Array, _third:SharedObject):Object{
this.ID = "myvalue" + _third.data["#ID"];
};

Using your code, I created the below test case. It's doing the same as your code, and is outputting the expected values.
package kazo
{
import flash.net.SharedObject;
/**
* ...
* #author KM
*/
public class TestCases
{
private var ID :String = null;
public function TestCases() { }
/**
* Start the test case
*/
public function start():void {
trace('Starting test case');
var SO:SharedObject = SharedObject.getLocal('TestCases');
if (!SO.data["#ID"]) {
trace('SO data not found, creating');
SO.data["#ID"] = '123';
SO.flush();
}
getID(SO);
}
/**
*
* #param _SO
*/
public function getID(_SO:SharedObject):void {
this.ID = "myvalue" + _SO.data["#ID"];
// trace = myvalue123
trace(this.ID);
}
}
}
trace:
(fcsh)Build succeeded

Starting test case
myvalue123
If you're still having problems, I'd suggest trying to call toString() on the value you're pulling, so:
this.ID = "myvalue" + _SO.data["#ID"].toString();
Should that still not work, store it in two separate String variables and then combined them.
