Default Table/Relationship Indetermined

Hi I am setting up a database to keep track of our training classes. I have
to track absences and count them for the week as well as a cummulative count.
When I am doing the cummulative count, it is counting all the absences for
their past classes and their current class. I think there is something wrong
with one of my tables.

Tbl_Associates
-Emp ID - Primary Key
-Last Name
-First Name

Tbl_Activity Info
-Course Title (there are 3 courses)
-Activity Code (Individual code for the particular class) - Primary Key
-Instructor Name
-Location
-Start Date
-End Date

Tbl_Activity Details
-Activity Code - Primary Key & One to Many relationship with Activity Info
-Emp ID -Primary Key & One to Many relationship with Associates
-PC#
-DN#
-Status (Complete, Incomplete, Drop)
-Withdrawl/Drop Reasons

Tbl_Attendance
-Emp ID - Primary Key - I feel like this should link to Tbl_Activity Details
but I get an Indetermined Relationship. I can link it to the Associates
table, but then when I go to count absences I can't count the total absences
on just this Activity, I get all activities they have been in.
-Date -Primary Key
-Week #
-Late
-Late From
-Absent
-Preplanned
-Time missed

Any ideas on how to fix this so I can group the attendance by the Activity
Code? I also have Weekly Progress reports that have to be done every week per
Activity and when I create my form, it get the reports for all activities,
not just the activity code I have them enter in the query. It's pretty much
the same problem, just different info no being able to group by Activity
Code. Please help!
