Hi there,
The section "Estimate the Cost of Shipping & Taxes" acts totally irrational.
The value of "Total" in the" Shopping-Cart Summary" page is not updated according to the shipping rate of selected delivery service from the "Carrier List" after pressing the "Update Cart" button.
It just adds the shipping rate of the Default service to the value of "Total Products" (btw. only after pressing the Refresh / Reload browser's button) and stays this way regardless of the selected alternative delivery service.
Please see slides in the attachment.
Please help or point out at the main files affecting this calculation.
Thank you,
Alex
