This has been discussed before but I would just like to know if there is any good reason for not using a standard text box to capture phone numbers in Machform.
This would allow the user to enter the number in pretty much any format they like without triggering an error message when the form is submitted.
As far as I can see the number would appear in the notification email and the Machform entries pages in just the same way as if it was in a Phone Number field. It would of course be labeled appropriately and therefore easy to identify for logic or other purposes.
Maybe I'm missing something but when I used to make my own HTML forms I always used a regular textbox for this purpose, so why not in Machform?
