Mask on Column for validation

I am attempting to apply a maks to a column but not having any luck.
This is the script I have,
fd.spRendered(function() {

fd.field('Title').mask = "(999) 000-0000";

I am trying to make sure that the user put the information in in the correct format

Hello @jktodd007,

The mask property is only available for the MaskedTextBox common field.

You can add this field to the form, and pass the value from it to the SharePoint field on form submit:

fd.spBeforeSave(function(spForm) {
     fd.field('Title').value = fd.field('MaskedTextBox0').value;
