Hi Everyone,

This is my first post, and I am not very technical. I have tried to respect the post guidelines. The contributors to this forum do an amazing job, and I salute (shoutout) you for that

I have tried to figure this out, with no success. Had a friend knowledgeable in php, etc. (but not ZC) look at it quickly, and he is stumped.

v139h fresh install (aug/2011) by zencart-templates.com
with Canada Post ship module, PayPal standard, french language pack
6 tax rates + 1 combined (not compounded)

php 5.2.17 / mySQL 5.5.19 (GoDaddy - 2G hosting) Database: MySQL 5.0.96

no commercial activity until March/2014

trigger - deleted PayPal Std & installed Express Checkout & Fedex plugin from numinix (I have followed the ec install guide on this forum to the letter. Have done the ipncheck & curl test, both with positive results.

2 payment options: Debit Card / Cheque / Money Order (this option works perfectly)
PayPal Express Checkout (logo on payment page is "paypal" (not express checkout)

have since uninstalled fedex & installed UPS XML

Canada post option is intentionally limited by weight

url: http://pollutionsolutions.ca/

when selecting ec on the shopping cart contents page, result is a blank page

error log:
PHP Fatal error: Unsupported operand types in /home/content//includes/functions/functions_taxes.php on line 172

here's line 169-172 from functions_taxes.php

// Calculates Tax rounding the result
function zen_calculate_tax($price, $tax) {
global $currencies;
return $price * $tax / 100;

on the Thread: Fatal Error? there is mention of Splittaxlines - my install works perfectly

I have searched exhaustively through the forum, but have not found anything that points to my specific problem

Any help would be greatly appreciated.
