Problem with redirect script - help!

Hi,

I got a tech guy to write (or steal - not sure how he got it!) a Javascript that redirects users to a different URL based on the browser or OS they are using.

I did this as some of the SEO code I use messes up the formatting for MAC and Opera users. Now however I need to use this script for all IE users but I've tried adding the variable to the statement about going to google.co.uk instead of the correct address and it hasn't worked.

Does anyone know how I can fix it so that the IE users go to google.co.uk instead of my page?

Any help appreciated (5pm deadline - sweating..)

Cheers

Paul

p.s. the redirect part is the last statement in the very very long script.

<script>

Good grief, Charlie Brown! This script doesn't just sniff browsers, it sequences their friggin' genome! This has to be overkill for any rational site design. Perhaps we should start from the beginning.

lol, yes he went a bit over the top with it thats for sure. I got the IE redirect bit working about 20 mins ago thanks, not quite sure why it wasn't working before but hey, it is now :-)

Now, I'm just going through it and deleting paragraphs at random and if it doesnt break it, it stays out lol.

(trying to get the page size down from 3 terabytes)
