Simple Script - JavaScript newbie...

[Dineen]

I don't know much at all about JavaScript, but I'm trying to do an image change on a link hover. The image changes on another part of the page. The error I receive is "document(...) is null or not an object".

Here is my code:

<script language=&quot;JavaScript&quot;>
<!-- Hide the script from old browsers -- >
img0_on = new Image(50,50);
img0_on.src=&quot;amy.jpg&quot;;
img0_off = new Image(50,50);
img0_off.src=&quot;dineenjohn.jpg&quot;;

img1_on = new Image(50,50);
img1_on.src=&quot;amyapril.jpg&quot;;
img1_off = new Image(50,50);
img1_off.src=&quot;dineenjohn.jpg&quot;;

img2_on = new Image(50,50);

img3_on = new Image(50,50);

img4_off.src=&quot;dineenjohn.jpg&quot;;

img5_on = new Image(50,50);
