Custom MC property seen as number instead of string

programming flash
1

Hi,

I’m trying to create some custom properties, but for some reason I can’t make them Strings.
If I give them a string value: “Something” it is returned as NaN by the MC.
But if I give it true; as a value, it is returned as 1.

this is in the class

 
public static var Temp_F:labeled_btn = new labeled_btn()

function setting the values

 
   Temp_C.btn_label = "C";
   trace ( Temp_C.btn_label ) **//<-returns "C"**
   Temp_C.btn_selected = true;
   Temp_C.btn_groupName = "temp";
   Temp_C.x = 70;
   Temp_C.y = 365;
   settingsBox.addChild(Temp_C);

Function in the MC

 
trace(this + "  = " + +this.btn_label+ " = " +this.btn_selected );
// **returns [object labeled_btn]  = NaN = true**

I don’t get it…
