I am trying to create a lookup from one Access table to a linked list from SharePoint. I need to have a lookup between the two because in order to create the type of subform that I need, there has to be a relationship between the two tables. However, the 'Relationships' button on the ribbon in Access is greyed out. It seems the problem may be that there is an error every time I open the linked list claiming that 'The setting you entered isn't valid for this property.' That confuses me a bit, as I haven't actually set any properties- it comes up just from opening the list to view. I tried creating a new database and linking the table again, but I still get the same error. I checked the column restrictions in SharePoint, and the only required columns have no blank values, so that shouldn't be it. There is one calculated column, but it relies only on the required columns. At this point I have absolutely no idea what is wrong. Any help would be appreciated.
BTW, there is no custom code running in the database- I've just created the database, created a table, and linked the list.
EDIT: Some additional information- I have already tried a Compact & Repair, but no luck. Also, I can reference the UserInfo table from SharePoint without any trouble.
