I'm not a javascript guy, but the use of this banner rotator script
has given me fits. I know a few causes of the problem thus far, one
being the layer tags aren't supported under Netscape 7.1 just the
entire 4.X series. Script works fine under IE. I've tried a few
things to get it working under Netscape, such as defining a style for
the bannerLayer with the style tag, and trying to define the style
under the div tag, I've tried the getElementById but that doesn't work
either or else I'm doing it wrong.
It errors out here with that document.layers has no properties error:
var layer = (document.all)? document.all.ba nnerLayer :
document.layers .bannerL
ayer.document.l ayers[0];
