So I have a web page which has javascript rollover buttons and an auto gallery which scrolls through pics automatically. I made most of this using dreamweaver as my javascript is quite sloppy. The problem I am having is, both sets of code works perfectly fine on their own. The rollover buttons work and the gallery, but when added together on the same page only the rollover buttons function and the gallery doesn't start auto scrolling at all. When i take away the rollover buttons, it works again. Any ideas of why this is happening?

Sorry guys, as embarrasing as it is, I couldn't get it right posting the code so it displays in colour lol. If anyone can tell me how I'll repost it quick.

You're binding two pieces of code to the document's onload event:

 

onload = function(){

if (document.images)

switchAd();

}

 

[...]

 

<body onload="MM_preloadImages('buttons/home.gif','buttons/gallery2.gif','buttons/products2.gif','buttons/contacts2.gif')">

 

The event can only be bound to one, so every time you bind it you're overwriting the previous handler. Move the MM_preloadImages() call into the anonymous function.
