BWAccess APV city state import

I am importing an Accounts Payable Vendor to BusinessWorks. The file is a comma delimited file. The definition says to send city and state abbreviation a City, ST for example Hastings, MN. When importing, this adds the city as "Hastings" and the Zip code as "MN". Zip code is the next field. Since we are adding a comma for the state abbreviation to a comma delimited file, BWAccess saves the state abbreviation as the zip code.

Please advise how to write this data so that the city saves to the City field and state abbreviation field to the State field.

Thank you.
