Hi, Thanks for you reply. Much appreciated. My problem is that when I click on the Select VAT box, nothing drops down. The box just stays the same.
If I try to enter a letter to prompt it, the letter goes red and I get a message saying 'please enter a valid code'. I've tried prompting the drop down box with every letter from A to Z and every number from 0 - 9, but get the same response.
I ended up going to the Bank Deposits screen and using the Add funds to this deposit and I was able to get it to accept without a tax code. However it would be great to know what I should actually do rather than this work around.
