Sorry - Netscape users would have had trouble seeing the output - but it's fixed now. It was fine in Internet Explorer and OmniWeb (a Mac OS-X browser), but Netscape is finicky about tables. Should work now. Please report any other problems. I've also added in about 4 more weeks of results. Thanks -- the url again: http://grimpeur.tamu.edu/cgi-bin/hwy47tt C.
