Hello, I'm trying to create a validation rule on phone numbers that only allows numerical characters and standard symbols (i.e.: ()- ). I used the following in the Error Condition Formula:
REGEX(HomePhone, "[^
\\D-()\\s]")
I didn't get any syntax errors, but after saving when I test it using disallowed characters I don't receive an error message. The rule is active. Anything I'm missing?
