I've changed a few things in the customer.itpl.php file, because it has too much information for my purposes.
But no matter what I do, I keep getting the follow error:
Parse error: syntax error, unexpected $end in ubercart/uc_order/templates/customer.itpl.php
The line number it gives is always the last line of the file. There is no extra whitespace at the end.
**Update**
Nevermind, I figured it out. I had a stray if statement that wasn't closed. Couldn't find it before.
