Hello Julie,
Select Maintain Specifications to launch the specification designer. In the designer, use File | Open to open the specification used to print your check. Click on the Spec List button to bring up the list of fields available to print. Open up the Vendor Information list and drag the field you need onto your specification. If you are unsure of which field to select, then, create a check for one of these vendors and print it out using the specification Full info - all spec codes to see which field you need to add to the form.
