SOS,trouble with the supplement.

<p>telephone is a required field and the format should be (###)###-####
Whatever I type in,the commonapp says the format is incorrect.I can not submit my form now.
(000)000-0000,000-000-0000,0000000000,all of these formats are incorrect,
Anyone know what's the correct format ?</p>

<p>(000) 000-0000 works for me</p>
