I added "sleep 10" to the end of the script, still no logged evidence that the setwakup.sh script is being run.

The following is the contents of the log file, showing my last two attempts at getting this to work. All of the logged results
are from the checklogin.sh script, none from the setwakup.sh script.

2015-08-08 10:12:58.001 No one is logged in.
2015-08-08 10:12:58.001 User script is not running and there is lots of time before it needs to start, shut down.
