An input mask for phone numbers
I have followed this tutorial: http://help.filemaker.com/app/answers/detail/a_id/5839/~/creating-a-data-input-mask-for-formatting-telephone-numbers and it actually works but I'm confused about one thing. It seems like you would place the calculated field of the mask over the input field for the phone number. But you can't enter any data into a calculation field. So what do I do to connect the final dots so that the user just enters a 10 digit phone number and when he tabs or clicks away it's formatted correctly. And then what if he wants to update that number later.
