crontab problem

One of my users is trying to run a PHP script via cron and the lynx -dump command but the script will not work. The script functions properly because called from the Web, it does what it should. Even called directly from the command line, it does what it should... The only time it doesn't work is when it is called via crontab.

The error that I receive via e-mail is simple:
Your terminal lacks the ability to clear the screen or position the cursor.'
I have been looking for more information on this and I am pretty sure that it deals with the crontab program, but I really can't find information on resolving the issue.

One suggestion from someone that I asked to look at it was to add this line to the crontab file:
termcap=xxxxxsomethingherexxxx'
But I'm not sure what to set the value at, or even if that has anything to do with it...

Any help would be appreciated.
