Good catch! Thanks. I was reviewing the lab and the results didn't look right. But they probably are. For some reason there are three sections in the lab that are almost identical and when I went to J6 I went to the wrong section to compare. Now I need to look at the lab a little more closely and see why there are three sections that look almost identical.
That's what I get for rushing. On Thu, Feb 24, 2011 at 9:16 PM, Dan T.
