In a Gift Export, you can select to export the Total Benefit Value field as an export field. If more than one benefit is listed on the gift, the amount in the Total Benefit Value field appears incorrect in the export.
The Total Benefit Value field is referring to the total value of each benefit on a gift. If more than one benefit is listed on your gifts, you will need to export the field multiple times. Then, each Total Benefit Value will be listed in a separate column. There is no Export field that sums the Total Benefit Values of all benefits on a single gift.
