AbleCommerce Shopping Cart Software

I'm getting "00 is not a valid unit of measurement for dimensions for this shipment" error when sending to UPS for shipping estimates.

Looking at the log file, I am in fact incorrectly sending <UnitOfMeasurement><Code>00</Code></UnitOfMeasurement> to UPS.

Looking at my other installation where it works, it should be: LBS instead of 00

Question is: where in AbleCommerce can I modify this?

In order to change unit of measurement for store got to store setting page under Administration > Configure > Store and then change measurement unit from Locale Settings section.

I think you haven't specified dimensions for product, so just edit product being purchased and shipped from catalog and provide some valid dimensions to it.
