Working with RegEx Validation on an SSN field in Forms, I am using the following expression
However, it only seems to except an empty field - and calls any other entry invalid. This is a generally accepted expression referenced in multiple places and I tested it in RegEx validators. The underlying field is Single Line of Text
What Am I doing wrong?

let us know what it ends up being!
