Hi Jack,

This occurs when

- Customer has an associated foreign currency
- A vat number is entered for the customer
-  EC Sales Tax Code is selected as the default customer tax code.

Remove the VAT number and it should let change it then add the VAT number back.

Thanks Ian, do all of the above have to apply for the box to be greyed out, or is it only one or another?

I do have other customers that have associated foreign currencies but this issue isn't present. I'll remove the VAT numbers and see if that works, and get back to you.

Hi,

All three of those criteria need to be met for the box to be turned off.

Thank you so much!
