Response time monitors

Hi all,

I cannot figure out how to get a device to generate an sms/e-mail when its response time exceeds its threshold.

I set the value on the device by editing the response time.
When I try to add a notification profile for the device, I expand
'when any [selected...] Threshold rule is violated'

However, when I click on selected it says that no thresholds have been defined.

Thanks for your help
