Hi all,

I am trying to build a validation rule with REGEX for the field Phone. The validation rule should check the following:

• Allow: Numbers
• Allow: Characters such as '+', spaces, parenthesis '(', ')', '/', '-'
• Allow: Character '+' should be only at the beginning of the phone number not in the middle or at the end

So, just searching pages with REGEX tutorials but unfortunately I could not find any appropriate in order to also decrypt the following expression literally:

NOT(REGEX(Phone,"(\\D?[0-9]{3}\\D?)[\\s][0-9]{3}-[0-9]{4}

")

)

No idea what do the following do?:

• \\D? (at the beginning and at the end)
• {3}
• \\s
• {4}

I would appreciate if experts in REGEX could give me some guidance here.
