There are a few "error undefined" errors found on my client's OpenCart store (see attachment).
Mostly on the following checkout URL:
index.php?route=checkout/checkout

Milestone #1:
Fix all errors on the checkout URL of the store (includes Register Account, Guest Checkout, and Returning Customer log in functionalities)
Make sure an order can be placed smoothly without any errors. You are done when the store redirects to PayPal link.
