Nested Comments Help

Hi there,

I have hit a wall trying to figure out the nested comment issue I am having. I am hoping that someone here can give me a little help. I am using the wp thread comment plug-in for my comments and nested replies. Every time I add a reply to a comment it’s treating it as a comment and putting it at the bottom of the comments list. I have no idea what is going on and would greatly appreciate anyone who could help. Thanks.

Here is an example of the problem by the way.
