Code Issue

So I have a problem. Someone helped me and told me to paste some code into my comments section of my template. The problem is that no matter what blog posting you post a comment to, the comment shows up under post=158. So if you respond to my most recent posting, then your comment would not show up there. It shows up under this old blog posting.

So I think the problem has to do with the “value=”158″ ” section of the code below.

<p><textarea name=”comment” id=”comment” cols=”100%” rows=”10″ tabindex=”4″></textarea></p>

<p><input type=”submit” name=”submit” id=”comment_submit” tabindex=”7″ value=”Submit Comment” /><input type=”hidden” name=”comment_post_ID” value=”158″ />
</p>

</form>

What code do I insert to make it generic and to understand that it just needs to post the readers comment under the blog posting that they are commenting to?

Please help.

Thanks!
