Shipping rate calculator for Canada
A tax calculator for Canada is implemented and working on the live page.
But after upgrading to MSQLi it no longer works. Both on the live test page and on the local test server.
It is set up to compare the first letter in the postal code. If only the first letter is used like "E", it calculates correctly, but if a full postal code is entered like "E7M 2M9", it returns a zero value.
