Hi Peter, I'm really sorry, I thought I was in plain text. I don't use any formatting in my emails and in Gmail the HTML looks the same as plain text.
Anyway, I've attached the data (I didn't think we could do that but I am frequently wrong). I say many cases because this is just a subset of >300 observations. The error seems to happen without a pattern I can discern. I am assuming I am doing something wrong.
