Validate number of digits (1 Viewer)

[sroot]

I have a form that a user has to type in a number in a text box. The number has to be 12 or 14 digits, so is there any way that if it is anything but 12 or 14 that a message box pops up and tells them to check the number and re-enter it? Thanks for any help!!!

if len(YourField)= 12 or len(YourField)= 14 then
' do whatever
else
Msgbox "Check Number"
end if

You can check with the Len() function in the after update even

If Not (Len(Me.YourTextBox) =12 OR Len(Me.YourTextBox)) = 14 Then
   MsgBox"Incorrect No of digits"
End if

Thanks that worked perfectly. I can't believe that i had forget to use"len". Thanks so much!
