How to validate valid phone numbers in the service catalog

[santrym]

I'm not seeing a phone number field type for user input. Does ServiceNow provide any kind of cell phone validator in the Service Catalog, or will I need to write a client script to do this?

Unfortunately there's no matching phone number variable type like there is for fields, so you'll need a client script to validate.

This was a tough one, because the answer I used was in the link you provided, but the answer I used was written by Brad. I'm gonna give you "Correct Answer" though for making it convenient for me. So, thanks Chuck for giving me the answer I needed, and thanks Brad for writing it!
