Those of you using DotComments with the new and "improved" blogger.com should note that you need to put single quotes around the <$BlogItemNumber$> where the href for the comments goes. This changes the BlogItemNumber into a string instead of a number and so with the new blogger format (as well as the old) it will count properly. Thus, it should look something like this:
<a href="javascript:viewComments('<$BlogItemNumber$>')"><? echo commentCount('<$BlogItemNumber$>'); ?></a>
