Mobile Phone Calculation
First i would like to say g'day to everyone and thankyou in advance,first post here and am a newbie to the program.
We sometimes have a problem with users and the entry of mobile phone numbers, ie: to many numbers or not enough numbers, so what i need help with is a field calculation that will notify the user if they have entered too many or not enough numbers and allow them to re-enter the number. We only need 10 numbers in the field.
I am not a programer so if someone could help with the steps of the calculation in dummie terms please that would be great.
