param := emp.:emp.LIST10%type;I'm not quit sure what you are trying to achieve with this.
If have build a poplist as a block-item you know the datatype of that item. When you know want to create a local variable to take the value from that list, either define it just with the datatype taken from the item, or take it dynamically from the column from the database the item is based on, so
DECLARE
  -- explicit
  vcParam  VARCHAR2(50);
  -- takeing datatype from db-column
  vcParam  TABLENAME.COLUMNNAME%TYPE;
BEGIN
  -- Assignment
  vcParam:=:EMP.LIST10;
END;
