This error occurs when Royal Mail cannot generate a label because a declared item value is zero or outside the accepted range.
Error message
"The ItemValue must range between 0.01 and 999999.99"
What this means
Royal Mail requires all items to have a declared value greater than zero. An item value of 0 or a missing value will cause this error.
How to fix it
- Review the item values for all products on the shipment.
- Ensure all items have a declared value greater than 0.
- Update the item value in the product catalog or on the order.
- Regenerate the label.
