Post comments glitch

I am using WP 3.5 and a modified version of this template. In default, the post comments are absolute positioned at the top of my posts, covering post content… I’ve been messing with the css for weeks, but can’t seem to get it working correctly, any help is much appreciated! here is an example of what happens after people start posting comments .. you are welcome to leave comments on posts to check it out..
