Lynx via crontab

I've written a program using the bourne shell (I think)
Code:
#!/bin/bash

that goes through a database and for each line does
Code:
lynx "http://www.example.com/test.cgi?var=variable"

The whole point of this was to later move it into the crontab so that once a day it would run this program on a website. Now that I've gotten all the bugs out, I can open my terminal and run the program. It comes up with the website using lynx and tells me I'm successful. However, when I moved it into the crontab it sent me an email saying Your terminal lacks the ability to clear the screen or position the cursor. I typed man lynx to see if there were any ways around this, and couldn't find any. It said something about -term, but I couldn't find enough info about it for it to make sense to me. Is there some way to make the program think my terminal does have those abilities, or to make it ignore that completely? Or maybe even make the program open up a terminal window and then run? I've searched this forum and other sites and my Unix in a Nutshell book, but can't find anything. Thanks a lot for your help and for having the patience to read this far!

OPENVT(1)							     Linux 1.x								 OPENVT(1)

NAME
openvt - start a program on a new virtual terminal (VT). SYNOPSIS
openvt [-c vtnumber] [OPTIONS] [--] command DESCRIPTION
openvt will find the first available VT, and run on it the given command with the given command options, standard input, output and error are directed to that terminal. The current search path ($PATH) is used to find the requested command. If no command is specified then the environment variable $SHELL is used. OPTIONS -c, --console=VTNUMBER Use the given VT number and not the first available. Note you must have write access to the supplied VT for this to work; -f, --force Force opening a VT without checking whether it is already in use; -e, --exec Directly execute the given command, without forking. This option is meant for use in /etc/inittab. If you want to use this feature in another context, be aware that openvt has to be a session leader in order for -e to work. See setsid(2) or setsid(1) on how to achieve this. -s, --switch Switch to the new VT when starting the command. The VT of the new command will be made the new current VT; -u, --user Figure out the owner of the current VT, and run login as that user. Suitable to be called by init. Shouldn't be used with -c or -l; -l, --login Make the command a login shell. A - is prepended to the name of the command to be executed; -v, --verbose Be a bit more verbose; -w, --wait wait for command to complete. If -w and -s are used together then openvt will switch back to the controlling terminal when the com- mand completes; -V, --version print program version and exit; -h, --help show this text and exit. -- end of options to openvt. NOTE
If openvt is compiled with a getopt_long() and you wish to set options to the command to be run, then you must supply the end of options -- flag before the command. EXAMPLES
openvt can be used to start a shell on the next free VT, by using the command: openvt bash To start the shell as a login shell, use: openvt -l bash To get a long listing you must supply the -- separator: openvt -- ls -l HISTORY
Earlier, openvt was called open. It was written by Jon Tombs <jon@gtex02.us.es or jon@robots.ox.ac.uk>. The -w idea is from "sam". SEE ALSO
