object variable or with block variable not set

[maxcess]

Not sure how the error started happening. Creating a new form with subforms worked without error, until at some point, the master/child link box returned this error. From what I have researched on this error so far, the underlying table properties are correct (required vs not required). There is nothing fancy here, though it appears to be broken on the second subform within the first subform. Using Access XP.

Oddly it was working before with three level subform.

Any general ideas?

Looks like a bug in Access at the third subform. As long as the editing is done with form and subform, the link build button works correctly.
