If you're on IE7 and reading this, which I was able to do, then I have the fix for all of us poor Blogspot folks out there. BRB-- (refresh, for the latest.)
h/t to Vman for the link to MS's error site. Gear heads can go there for the same clue.
In a nutshell, the sitemeter link is usually in one of those "page element" boxes called widgets. You gotta select the "blog post" part of your layout, then find the tab up top that says "Edit HTML". BEWARE!! You MUST save your template to your desktop BEFORE farkin' around with your templates mysterious innards!
In a separate tab, go to sitemeter.com's management page for your site and copy the html text you normally have in your widget.
Now go back to your template and scroll all de way down, mon. You'll see the last few lines will have these words inbetween the carat thingies:
or some such.
The dealio is, place your cursor just before that text, < "/body"> and paste. Do a preview of your page, scroll all de way down, mon, and you should see your sitemeter sitting pretty down there. (You can place it anywhere, but if you don't know what you're doing, just go with what's easy.) Save it. If you messed up, you can reload your template and all will revert.
IMPORTANT! Find the widget page element that has your HTML script in it and remove it, then hit publish. Not as hard as it sounds. If you get stuck, email me.
Hope it works, kids.
