We have a form which includes a phone number field embedded in our website. The phone number field is required and it shows the required error if I lose focus of that field. But if I fill-in illegal characters in that field, such as letters, it doesn't show the error of it only allowing the characters that are legal for the field type. Even though no error is displayed, if you fill-in illegal characters you are not allowed to submit the form, leaving the visitor confused why he can't submit the form.
The form in the sharable link however does have the error displaying when I fill-in illegal characters. Does anyone know if it's possible to show the error in our embedded form?
