Comments.php….HELP!

‘ello wordpress world,

I am part way through making my first comments.php template and am having trouble. I currently have the style of the form complete and it looks fine in my browser, but what I am struggling with is creating a functional comments template using PHP. I am no PHP programmer.

I am primarily focusing on creating a functional comments form before I move on to the rest of the template.

Could someone point me towards a beginner/intermediate level tutorial on how to get the PHP to do what you want in the comments template? I’d especially appreciate one that breaks down the main functions with line by line analysis of the source code.

Any and all other help/advice/tips are greatly appreciated, I feel like I’ve hit a brick wall. >.<
