Hi spurr82,

In the 'Sites' list, try changing the 'Developername' column type to Lookup.

In your third list - 

Column 1: Set the source as the developers list. Use blank as the parent field and specify the child field as Column 2.

Column 2: Set the source as the sites list. Use Column 1 as the parent field and the child field leave as blank.


Hope this helps.

I was getting this error after creating a list that implemented two cascading drop-down columns.  After hours of investigation and configuration checking, I narrowed the problem down to another list that was the source of the values for the first cascading dropdown.  I finally discovered that the column being retrieved had apparently been renamed from "Title" when the list was created.  I changed the display name of the column back to "Title" by editing the list column in the UI and the cascading dropdowns worked.
