No matter what i try, i still can't get them to match the regEx string.  I know there is some javascript, but i hope with the amount of jQuery i am using that i can post this here.  Is there something simple I am missing or is my concept wrong or  do i just keep using incorrect regEx strings?  Any help would be much appreciated.  

Thanks, 

Eric

2.         var phoneExpression = new RegExp("\d{3}-\d{3}-\d{4}");
3.         $('.PhoneNumber').each(function () {
4.             if (phoneExpression.test($(this).val()) == false) {
5.                 $(this).addClass('MissingData').addClass('HelpTip').prop('title','Format number as xxx-xxx-xxxx');
6.                 isValid = false;
7.             }
8.             else {
9.                 $(this).removeClass('MissingData').removeClass('HelpTip').prop('title','');
10.             }
11.         });
