Good morning! That worked - you are a genuis! Thank you so much for your time and help! 😁
The formula: Formatted ZipCode = IF([RecipientCountry] = "United States", CONCATENATE(LEFT([Zip Code],5), CONCATENATE("-", RIGHT([Zip Code],4))), [Zip Code])
I hope this helps anyone that want to format US- and non-US zip! Thank you again, Vicky. Have a great rest of your morning and day!
