Hi Developers,Need a help to achieve below functionality. how to write a validation rule such that it should not allow any special characters(!@⌗$%^&*) and not allow all zeros in a field. (eg: 0 or 00 or 000 or 0000). I have used the below validation rule that is restricting special characters but allowing all zeros. NOT(REGEX(Phone__c,"^[a-zA-Z0-9]*$"))
