Question : Validation in a form - Using "len"

Hi,

This should be very easy.
In a form I want to force my users to key 9 characters exactly into a field [SCV_Number].
I am using the "Property Sheet" for the field and there is an option for a "Validation Rule".

What syntax do I use to say len[SCV_Number] must equal 9??
I find the expression builder confusing in this case.
Thanks,

Len([SCV_Number])=9
 or you can use Input mask
