Shipping Surcharge [Support Thread]

[njcyx]

I'm looking for a module for "tariff surcharge" and this module looks good.

I tested it under zc158 and it shows some warning.

--> PHP Warning: A non-numeric value encountered in /includes/modules/order_total/ot_shippingsurcharge.php on line 78. 

Line 78 is the following.

$shipping_surcharge = ($order->info['subtotal'] * (MODULE_ORDER_TOTAL_SHIPPINGSURCHARGE_AMOUNT/100)); 

My fix. Change this line to

$shipping_surcharge = ($order->info['subtotal'] * ((float)MODULE_ORDER_TOTAL_SHIPPINGSURCHARGE_AMOUNT/100));

Line 89 is the following.

$order->info['tax_groups']["$tax_description"] += zen_calculate_tax($shipping_surcharge, $tax); 

Not sure how to fix it. My fix is to comment the this line out. It seems no affect on my checkout page.

Also this surcharge doesn't apply on my sales tax (local sales tax), which seems normal anyway, since it is a surcharge.
