Problem
You filled in all fields in the Add VAT rate dialog and clicked Add, but nothing happened — no notification and no new entry in the list.
Possible cause
The form validates three fields: VAT name, VAT (%), and VAT account number. All three must be filled in with valid values. The system also checks that a VAT rate with the same percentage and account number does not already exist.
Solution
Check that the VAT name field contains at least one letter or number — special characters do not count.
Check that the VAT (%) field contains a number between 0 and 100.
Check that the VAT account number field is filled in with a valid number.
Look for red error text below each field — it tells you exactly what is missing.
