So when ever you want to set the property to any HTML element in javascript, first check that if it is defined yet or not and apply properties only when they are defined.

javascript Syntax (Toggle Plain Text) 
  1. if(document.banner)
  2.      document.banner.src = bannerRotate[ getNewBanner ];
so you meant that the problem is from this code??

Ok, is it necessary to use that code?
javascript Syntax (Toggle Plain Text) 
  1. if(document.banner)
  2.      document.banner.src = bannerRotate[ getNewBanner ];


please could anyone explain to me just why we used (document.banner.src)???
it is not defined I mean in my whole code there's no (banner) so where did it comes from? and how it works?

thanks in advance will be much more appreciated..
