Discount coupon bug on canadian taxes?

[icikite]

I need help to fix this problem.Thanks for looking.

Discount coupon setting:
include shipping true
include tax false
rec-calculate standard

Here are the results . Note if you add the total PSt and the total GSt you have the correct result but the Pst on the sub-total - discount should be 18.45 and 1.50 for the shipping . It seems that it apply the discount proportionaly between sub-total and shipping.Also the total is .01 difference. should be 450.36 if you add the total

sub total 399.00
flat rate 30.00
discount -30.00
gst 5% 18.55 should be 18.45
pst 7,5% 29.22 should be 29.06
gst 5% 1.40 should be 1.50
pst 7,5% 2.19 should be 2.36
total 450.37 should be 450.37


Thanks and Thanks.

Are you sure your tax calculation problems aren't a result of the changes you've made to the tax-calculation functions? http://www.zen-cart.com/forum/showpo...7&postcount=13

Yes it make no difference.
But I resolve the problem by making all taxes calculate with the same tax classes. So now I don't have the taxes on four lines but on two lines and they are correct.
Sorry to not try that option before making this tread.
Thanks for looking.
