Contents of confirmation email?

Hi,

I once screwed up the check out sequence, so I recreated it.
Now it seems it's all working (thankfully) and confirmation email for me and custmer are sent fine as well.

The problem is, that the contents of confirmation email seems different from the past (when I first made the sequence.)
I remember that I used to have the order detail, and customer detail. Now, I see what's typed in checkout form, but not with the label that I customized.

I opend "Blank.php" and tried edit, but can't see any element for that area.
I'm probabbly missing something or I just can't remember what I used to do, but now I'm stuck.

I tried to edit confirmation email from Server Behavior panel, but it doesn't let me change the contents anyway.
How can I edit it so I can put order dtail and customer information?

Thank you for your help.
