Hi

After install the "OWC EU VAT Compliant" and setup all settings. Then in checkout, the custom field and the check works, but then I should continue with the checkout and press continue, this error is coming in the log. And the process to continue the order is halted. It will not continue to last checkout page.

I have OC 3.0.3.7. Using Marketing SG Quick Checkout.
I think I have all your modul-parts installed.

If I use the standard checkout it looks it works as it should. So problably is something with "OWC EU VAT Compliant" and "Marketing SG Quick Checkout".. It can also be some other module interfering, but I need to start somewhere, and this is the last module installed.
