Strange question Cron problems

Josh, That would probably help right? I have been trying it every way I can think of. Each time I change it I run /etc/init.d/crond restart Not sure if I have to but it can't hurt right.

 cron tab for root
1-59/10 * * * * /usr/bin/diskmonitor
0 */4 * * * /usr/bin/diskwearoutstat
50 20 * * * /usr/bin/updatecheck -a
50 20 21 * * /usr/bin/phonehome_activate
*/5 * * * * /home/Joe/Temperature.sh
 block 395320 

*/1 * * * * /usr/sbin/lsusb -v -d 0451:3410 >/dev/null
 end 395320 
MAILTO=""
54 * * * * /usr/bin/copy_rrd save

It is the /home/Joe/Temperature.sh have also tried running it like

*/5 * * * * /etc/cron.hourly/Temperature.sh

As well as

*/5 * * * * root /etc/cron.hourly/Temperature.sh
*/5 * * * * /home/admin/Temperature.sh
*/5 * * * * root /home/admin/Temperature.sh

The script has to write a file locally and it can't seem to write it in cron.hourly so I keep moving it around. So the script runs a grep and writes a file. When it is in my home directory or home/admin it does the grep and writes the file but doesn't email it. If I copy the command out of the script and run it it will email the file as me or as root? Probably something stupid but I am stumped... Thanks for your help. Joe
