I tried writing a test function that just calls the existing function
so it should give the same results.
jQuery.validator.addMethod ('ccard', function (value, elem)
{
return (jQuery.validator.methods.creditcard (value, elem));
}, 'Enter a valid credit card number');
Unfortunately it didn't work, it just caused firebug to log an
error.
"this.optional is not a function"
