Zen Cart 1.3.8a on Local (not live yet, still learning).

I've done all the security patches, and I'm doing the fixes in the "Known Bugs (and fixes) with v1.3.8 / v1.3.8a" thread. I've reached post #27, about the $0.00 Gift Certificate balance, on page 3. It doesn't tell me where in general.php to add the function shown in the post. I don't want to add the code in the wrong place and mess up everything.

I've found the section // Update the Customers GV account on line 1695, but I don't know if the code goes under there, or maybe it should just be added on at the very end of the file. May I have some direction on this? Thank you for your time.
