I don t have flap threshold's defined within the service it self, i just add

 flap_detection_enabled         1

to all the services i want to turn flap detection on for.

and the following is in my nagios.cfg file,

low_service_flap_threshold=5.0
high_service_flap_threshold=20.0
low_host_flap_threshold=5.0
high_host_flap_threshold=20.0

Hope this helps.
