ZAM ver 7.5

I'm in the Web Console and I've created a custom report that includes 2 UDF
(User Defined Fields). When I run the report the listing of all the assets
shows 0.0 in every Purchase Amount field and 1/1/1980 in every Purchase Date
field. If I click on the link for one of my workstations to open the detail
screen, the correct information is listed in those 2 fields. What can I do
to get the values of those 2 fields to show on the listing screen?
