Validate Phone Numbers
I have used the phone number validation in my form, but I would prefer for the validation to be 123-456-7890 instead of (123) 456-7890. How can I do that? Also, is there a way to force the correct input, i.e., they type in the first three numbers, it automatically adds the "-", then another three, auto "-", then last four numbers and not allow anything further. Can that be done as well?
