Hi Mike,
I have been playing with this and I am running into trouble.
Basically I output my new javascript into the body of my html, like so:
<scr*pt l*nguage="j*vascript">
alert('fired 1'); $('#slideShowasset1').innerfade({ animationtype: 'fade',
speed: 'slow', timeout: 1000, type: 'sequence', containerheight: 'auto'});
</sc*ipt>
Firefox will behave properly, but safari and IE 6 don't do anything.
What am I missing? Thanks a lot.
