Working on my very first Ubercart for a friend, and unfortunately, someone else had it partially configured before I came along. He was doing well, but got deployed to Iraq 
I have managed to add two products for testing, and the two products are showing. However, if I add product to the cart and press "Review Order", I get the following error message:
Fatal error: Call to undefined function uc_taxes_calculate() in /home/dirtydim/public_html/sites/all/modules/ubercart/payment/uc_paypal/uc_paypal.module on line 1182
I have gone through workflow and actually removed the taxes calculate condition, there was a rule in there to check for what "zone" or state the buyer resides in so it would charge sales tax if the buyer is in Tennessee. I removed it because I got this error.. But the error remains.
What am I doing wrong? How can I get the cart operational at this point?
If you need any further information, just let me know, not sure what all to provide to get the help I need for this one..
Thanks,
