I copied this from my working example and tweaked some lines to make it generic. Thus there MAY be a typo which I haven't checked for, but probably not. This is what's needed to have something change upon selection of an item in a ComboBox.

Copy this code and paste it in your HTML 
  1. // this code assumes the existance of a ComboBox (Components -> User Interface -> ComboBox) 
  2. // on the stage with an instance name of "MY_DROPDOWN_INSTANCE_NAME" plus two items defined in its properties
  3. // named "Choice One" and "Choice Two"
  4.  
  5. var MY_DROPDOWN_LISTENER:Object=new Object();  // a new listener
  6. MY_DROPDOWN_INSTANCE_NAME.addEventListener("change", MY_DROPDOWN_LISTENER);  //add listener to combobox
  7. MY_DROPDOWN_LISTENER.change=function(){  //function called
  8.     // do something based on the selected item's label
  9.     switch(MY_DROPDOWN_INSTANCE_NAME.getSelectedItem().label) {
  10.         case "Choice One":
  11.             trace("one");
  12.             break;
  13.         case "Choice Two":
  14.             trace("two");
  15.             break;
  16.     }
  17.  
  18.     // do something based on the selected item's value
  19.     switch(MY_DROPDOWN_INSTANCE_NAME.getSelectedItem().data) {
  20.         case "Choice One":
  21.             trace("one");
  22.             break;

  24.             trace("two");
  25.             break;
  26.     }
  27. }
