I just installed wp-invoice and so far it looks promising. One of the problems I've run into, however, is I'm trying to display the total balance due for the currently logged in user. One of the things I tried, was including the wpi_template_functions.php in my themes functions.php and then called the balance_due(); in my header, but I am only able to get a dollar sign ($) returned. No value or amount.
Any ideas on how to make this work?
Also, I was wondering if there was a way to check if a user has a new or unpaid invoice and leave a notification icon for them to see?
Thanks in advance for the help, Bc.
