Hi, I want to install the tracker on my Livejournal page but I'm currently using the custom external stylesheet for my page, so I'm not sure where to paste the code. And another thing...Livejournal doesn't seem to support HTML. Help, please?

I think that the tracker only works when put in the S1 style system on LiveJournal. So, unless you want to revert to the old style system, you're shit out of luck as the S2 style system only allows for CSS modifications and no HTML, as you seem to have discovered.
