How to validate field that is not required

-

i have form im trying complete before pilot....
its field not required complete form, need
contain numbers.

since not required.. how can validate if completed,
contains numbers?

using asp, sql2005 , dw8


which dw? if cs3, believe can use spry validation on field
check invalid input though it's not required. - form
validation should server-side.
