The MDX function failed because the coordinate for the 'PARENT ID0' attribute contains a set.

Hi, I am getting the above error when I run the MDX below, and I'm finding very little help for it in my searches.   What puzzles me is that if I comment out the bolded lines, the query runs fine.   I don't see what's different about the way that filter is constructed, versus the way the others are constructed, but apparently that one is a problem and the others are fine.\

Any ideas?
