   2 <p>This menu allows you to keep the data from the existing
   3 database. To preserve the data in a field, you must map it to a new
   4 field, where the data will appear. Any field can also be left blank,
   5 with no infomation copied into it. Any old field not mapped to a new
   6 one will be lost and all it's data removed.</p>

   8 You can only map fields of the same type, so each dropdown will have
   9 different fields in it. Also, you must be careful not to try and map
  10 one old field to more than one new field.
