On a Microsoft Access form field I can enter a PO number (ex. 123) that is looked up by a query with this code [Forms]![dates].[txtPOs] and it works fine but only if I enter a single PO number.
However if I enter multiple PO numbers in the form field it will never work, even if I enter the POs as "123 Or 124". If I go directly into the query and paste "123 Or 124" in the PO field (in design view) it will work.
