When you set up Area 1 ex $5.00 on total above $15.00 (That's works fine)
However, when i to add delivery area 2 or use Area 1 additional delivery to reflect different delivery charges bases on total amount above. It doesn't work. It will only keep reflecting the first delivery charge amount $5.00 on total order above $15.00. I didn't think this would be an issue since you coded the script to be able to perform this task. Please see attached in email.
Delivery Area 1
$5.00 on total order above $15.00
$25.00 on total order above $100.00
$30.00 on total order above $300.00
What I'm trying to do is charge customers a higher delivery charge if the total order amount exceeds $15, $100, $300
