i have to scripts : 

1) <script src="js/jquery-1.6.3.min.js"></script>

2) <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>

They are for slideshow

If i delete script 1 then slideshow 2 works fine. If i delete script 2 then slideshow 1 works fine.

But if i keep both scripts then non of two slides work:/
