This order form needs to be modified.
There are TWO sales tax rates, One for Ontario (HST 13%) and one for everyone else (GST 5%)
[url removed, login to view]
When customer enters his province, if it is Ontario the form needs to calculate the HST on $35 which is $4.55 and insert that in total box in the credit card order section, or if anywhere else the form needs to calculate GST on $35 which is $1.75 and insert that total.
Simple and straightforward
I want to be able to copy your code into some similar order forms
