Cron task output is 0, script output is OK

I have the following cron task set to run every 15 minutes to ascertain how many users are in the system and append the result to the log.

/home/pronto/cus/whoisinc >> /home/pronto/cus/whoisin.log

This is the whoisinc script

date +"%d-%m-%Y,%k:%M,Pronto Users,`prowho -s | grep -v SESSION | wc -l`"

Running it manually to screen I get the following which is what I want
20-10-2010, 8:55,Pronto Users,31
When cron task runs it, I get 0 every time
20-10-2010, 9:15,Pronto Users,0

What am I doing wrong? Can anyone help me?
