Unable to link two tables

By eckardtk ·
I have a main table/form called Contacts with details about persons and companies. I want to have a second main form that tracks the scheduled events such as presentations, workshops etc as well as who is going to attend (subform).

I have been able to establish most relationships. The remaining problem is that I cannot link EventId (PK) from table Event- Schedule to EventId (FK) in table Attendance. When I click Create, an error message pops up:
?Access cannot create this relationship and enforce referential integrity ??

Here is the overall layout:

Table Contacts
PK = Contact ID

Table Attendance
PK = Attendance ID
FK = Contact ID
FK = Event ID <== problem

Table EventSchedule
PK = Event ID < == problem
FK = EventType ID

Table EventType
PK = EventType ID

The grand scheme is to set up two main forms for data entry:
- Contact Details
- Event Participation

The Event Participation form would consist of two parts:

(a)Main form = description of the event; based on the table EventSchedule

(b)Subform = who is going to participate; based on table EventAttendance. There is also a lookup field in the subform which is linked to table EventType.

How can I make this work??

Besides the point: I tried to copy and paste a screen shot of the tables window here but I am unable to accomplish that. I had saved the screenshot as a Word file.

figured it was something simple, because it seemed that you had eveything done right.

You should hand out a few thumbs for this thread... :)
The other lads deserve thumbs as well for eliminating any other potential problems!
