Send Alert Until Error is Cleared

I've setup a monitor to run a script on a remote Solaris server every 2 minutes. This script checks /var/adm/messages for errors. If error is found it will create output file with value of "1" if not, the output file will be "0". It's setup to send Alert if value is "1". It used to keep sending Alerts until the errors is cleared, now it only sends one Alert. If it runs every 2 minutes, and the error still exists, shouldn't it continue to send Alerts? In Admin, selecting "Execute actions repeatedly if the Health is Critical/Warning (until it is clear)" did not help. This used to work before I purchased the license.
