   This is a common problem and a pain to debug. The problem is that the 
shell environment created by cron isn't identical to your login shell, 
missing things like environment variaqbles. Try using the full paths to 
executables in the shell script, in case they are not defined, and try 
setting debug lines in the shell script to see how far cron is getting, 
lines like:

echo "Reached line 23" >> /home/hyi/debug.log

   Yours,
