Lynx is a *nix console (simalar to a dos screen, much much better) based web-browser.
The script requires that the path be set to the location of lynx (IE, what directory it is in).
To find out, use the whereis command
EG
[mylogin@ctdadmin1 ~]# whereis lynx
lynx: /usr/bin/lynx /etc/lynx.cfg /man/man1/lynx.1
Note, that in the output,t here are a few entries. The first one, is most likely to be the one we want, as it is in a "bin" (binaries) directory.
So you would set the line int he config file to
set lynx "/usr/bin/lynx"
