I've got the right help, but not help you are going to want to hear--I think you have set up your database tables incorrectly.
The little we have to go on raises a lot of red flags. The Detail section doesn't use any data from the report. It uses DSums which have their own data source. Further, DSums don't just retrieve data, they aggregate it which is odd for the Details section. Lastly, you've hard coded your categories into the report (e.g. Equipment, Vehicles, etc). That information should be stored in a table itself, not hard coded and extracted with a series of DSums.
The ultimate report you create should use neither Dsums nor hard coded labels in the Details section--it should pull of its data from the reports datasource.
Can you post a screenshot of your tables Relationships so we can see the structure of your tables?
