Using Dlookup To Cross Reference Between Two Tables

I'm new to access and need to modify an existing database to get a report I want to create. I'm an Excel user and could accomplish what I want to do in seconds using Excel's Lookup functions, so I'm trying to do the same with Access Dlookup.

I have two tables in my database that tracks components in a hardware product. The first table is just a list of hardware units shipped. The second table is a list of various components (and versions thereof) used in each unit. The two tables are linked by a UNIT_ID field. I need to create a report showing each unit and what the various versions of the components are. My difficulty is that the component table is does not have a dedicated field for each component and each unit can be comprised of a different quantity of components. So the tables look something like this:

UNITS TABLE:
ID Customer
1 Joe
2 Bob
3 Bill

COMPONENTS TABLE:
ID Component Revision
1 Main Board A
1 Blue Board B
2 Main Board B
2 Blue Board B
3 Main Board A
3 Red Board C

I want to produce a report that looks like
ID Customer Main Board Blue Board Red Board
1 Joe A B --
2 Bob B B --
3 Bill A -- C

I setup queries to get revisions of each Board and am trying to compile into the full report, but can't figure it out. Right now I'm trying to use Dlookup to lookup data from one of the queries and insert into a larger table. I can lookup a single value fine, but can't figure out how to get Dlookup to give me the Blue Board & Red Board values for each of the system ID numbers in a master query (which would be a snap in Excel).
