What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I am not quite sure if I understood your concern correctly, could you please confirm. When you enter the verification code generated by the "SMS Confirmation" widget, it shows an error when you enter an invalid code? That should be normal if the code is invalid, I presume you meant valid code?
If you could share us a screenshot of the problem or the error code, that would also help us better. We'll wait for your response.
