I am using Amsty shipping table rate extension for shipping rate calculation.
Also am using TinyBrick extension for back-end order edit.
Once i edit the order in back-end, some amount ($-Grand Total) will increase. Now that time shipping rate is not changed for current amount ($-Grand Total) its showing old shipping rate.
(I am edit the order in back-end, After submit that page that time, i got $Grand Total, $country_id, $region_id, $postcode, $region, $city. How i calculate new shipping value for new grand total.)
How to fix this issue.
Please help me..
