Hi 
I need to check a checkbox field "Has Phone" if the phone number field as at least 5 digits 
( The reason for 'at least 5' rather than just 'not blank' is to avoid including "1" and the reason for  '5 numbers' rather than '5 characters' is to avoid including words like "no number") 

We're just trying to check if the contact has a valid phone number but we want to leave the sales people the ability to write anything in the field like reception, ext., etc ... 

Any ideas ? 
Thanks a lot
