Mark,

Does it work when you omit that individual?

If so, I would go through that ID's data records with a fine-toothed comb
to make sure their wasn't a 0 floating around somewhere that it shouldn't
be thats causing a divide by 0 error or some other data error.

The other thing that I might look towards is are you using a log
transformation somewhere in your code, possibly a negative number or 0 is
entering in somewhere, which can cause this error.

Tricky indeed,

Devin
