The following picture is for a phone number field that stores the digits only. By using the R function, preceded by the @ symbol in the picture, the literal characters in the template are not stored in the value, and are inserted when the value is displayed:

@R (999) 999-9999

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
