2. If you haven't set anything yet, select one of the fields two fields, Is Equal To, the {?Date} parameter.
3. Click on the Formula button to show what you just created.
4. Click on Edit Formula.
5. Type " or ", add the second field = {?Date}.
6. If you have other selection criteria, be sure to surround this or statement with parentheses.

{MyTable.purchaseddate} = {?Date})
