Did you have some mods already in affecting your admin/orders.php? Around your line 184?
I got an error
Code:
Parse error: syntax error, unexpected T_CASE in /home/.../orders.php on line 195
and when I looked it it, there is a chunk of code which appears to be something to do with editing orders rather than referrals, and which isn't in the original ZC1.3.7 file.
