Target of assignment must be a reference value. Issue

Question

So I have this issue I have never seen before and am unsure how to solve. I might be dumb but Im pretty sure I can do this. any ways can some one tell me why the following throws a Target of Assignment must be a refrene value?
public class test
     private var t:Test = new Test();
     private var fName:String;
     private var xml:XML;
     //For this example assumewe set a value of apples.XML to fName
     public function get fileName():String
          return fName;
     public function loadFile(fileToLoad:String):Boolean
          //open the file and return true or false if it exists and
          //can be opened.
     public funtion returnObject():XML
          if(loadFile(t.fileName) = true) // Target of assignment must be a reference value.
               //load objects into xml
               retun xml
There is a reason I am doing it this way. How ever I am not here to disuss that I am here to discuss why I am getting this error. loadFile(fileToLoad:String) takes a string, I am essentially giving it a string...So whats it's issue?

Answer 1

that's not a valid as3 class.  you need a package designation and a constructor.
package{
public class test
     private var t:Test = new Test();
     private var fName:String;
     private var xml:XML;
     //For this example assumewe set a value of apples.XML to fName
public function test(){
      public function get fileName():String
          return fName;
     public function loadFile(fileToLoad:String):Boolean
          //open the file and return true or false if it exists and
          //can be opened.
     public funtion returnObject():XML
          if(loadFile(t.fileName) = true) // Target of assignment must be a reference value.
               //load objects into xml
               retun xml
