Dave,

   I usually create a corresponding "cron log" for a
crontab script which could be something like this
using your example (of course below is a single line,
just wrapped by the email program in this case):

0 12 * * * sh /home/dave/myShellScript.sh >
/tmp/myShellScript.sh_cron.log 2>&1

   If there is no script "cron.log" output in /tmp
that would indicate the script isn't being executed
(examples - cron not running, pathing problem of the
script itself). If the script is being executed, then
errors from it should appear in the log file which
most probably would help to debug it. 

   By temporarily adding -vx (either within the script
itself or to the sh in the crontab entry) will provide
more information if needed.
