Problem
You tried to enter a VAT percentage, but the field does not accept your input or marks it as invalid.
Possible cause
The VAT (%) field only accepts numbers between 0 and 100. Negative numbers, values above 100, letters, and special characters are not allowed. Decimals are allowed using a full stop (e.g. 12.5), but not a comma.
Solution
Enter only a number between 0 and 100.
Use a full stop (.) as the decimal separator — not a comma.
For example, type 25 for 25% or 12.5 for 12.5%.
Remove any letters, commas, or special characters from your input.
