Hi,

I'm trying to apply a tax rate to an order only when the subtotal for the items in that tax class is above a certain amount.

Is www/shop/includes/modules/order_total/ot_tax.php the right place to try to modify the tax calculation logic or am I barking up the wrong tree? It seems to me that function process() in that file communcates that?

Any guidance appreciated.

thanks,
Don
