Adding and removing listeners help please...

Question

hi guys i have a pop up box that adds a listener depedent on a variable.
like such
     if(upload_typ != 'O' && upload_typ != 'E')
    {RPanel.DSUB.addEventListener(MouseEvent.CLICK, DatabaseSend)};
   if(upload_typ == 'O')
    {RPanel.DSUB.addEventListener(MouseEvent.CLICK, DataSendOntme)};
    if (upload_typ == 'E')
    {RPanel.DSUB.addEventListener(MouseEvent.CLICK, EncumSendVal)}
how do i remove the listeners? i continue to see examples of removing listeners but yet i dont see what the remove listener functions should do.
  any help would be greatly appreciated.

In your case, because you can't be sure what listener was added, you can remove them all, and if they have not been added, no harm:
RPanel.DSUB.removeEventListener(MouseEvent.CLICK, DatabaseSend);
RPanel.DSUB.removeEventListener(MouseEvent.CLICK, DataSendOntme);
RPanel.DSUB.removeEventListener(MouseEvent.CLICK, EncumSendVal);
Alternatively, you could register the ones that actually get added to an object (associative array) and remove only those when necessary.
