Thank you, Andrea.  I tried that as well.  When I try to insert, my code 
writes out

../../vpmultif/VpEpetraUpdaters.h, line 627, 
error 2 in replacing row of global index 100 for [indices, vals] = [100, 1].

So the return value is 2.  So then I try to insert, and I get

Trying insertion ...failed with res = 3

Is there someplace to look up these error codes?
