I have 2 fields, the user must type 10 numbers on it.
I want if user type 8 or 9 numbers on that field show a custom dialog and user know must edit that field.
user type: 001537996 <<<< it's wrong
true is: 0015379965
I think I use if and end if and show custom dialog but I don't know wich function I should use in if function.
thanks for helping
