    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Place a field where the response to our ASK field will be placed
    FieldRef fieldRef = (FieldRef)builder.InsertField(FieldType.FieldRef, true);

    FieldMergeField fieldMergeField = (FieldMergeField)builder.InsertField(FieldType.FieldMergeField, true);
    fieldMergeField.FieldName = "Column 1";

    // We can modify or override the default response in our ASK fields with a custom prompt responder, which will take place during a mail merge
