Validation rules for ms access

[helponmacro]

Hi - I've a database to input all order received by date.
I want to set a validation rule on the targeted payment date to be within a range of these rules:
Can be = today's date; or
Within 3 days before or after the order date.

Is there any way we can set such validation rules on these date range?

Ignore - misunderstood Q

In your Access Table Design, there is a line for validation rules. Highlight your field and then in the properties section below set your validation expression.
