Since I am missing latitude and longitude data, I tried to augment the missing field as the instructions advised. I added the city and state fields, specified a name for the new filed, and clicked on augment. Each time, I get a failure and the field is empty. The field type is marked as location, but one cannot toggle it to a different type, as one can with the others (which are marked as text). I even went back to the sample postcards .xls file provided in the "getting started" area of Viewshare, and this also did not work.
