You’ve imported a custom web form, but the submit button is not recognized by Acoustic Campaign. Because there is no recognition, an error occurs that causes the custom web form import to fail. Why?
The error occurs because Acoustic Campaign supports the <input> HTML code as: <input type='submit' value='Submit'> for the Submit button in a custom web form.
All other types of submit button codes are not supported, such as <button>:<button type='submit' value='Submit'>Submit</button>
In this case, if you are using other types of button code like '<button type='submit' ... >', you must work around this issue by changing the code to '<input type='submit' ...>'.
