Question about PING command

Hi !!!

I declare the PING command in my Netsaint over Linux , with th following
line in the hosts.cfg

service[buesisln5]=PING;0;24x7;3;2;1;;120;24x7;1;1;0;;check_ping!100.0,20%!500.0,60%

and I had the following warning messaje

SERVICE ALERT: buesisln5;PING;UNKNOWN;SOFT;2;-c: Warning threshold must be integer or percentage!

I don't know what' s it means?

The same command in a Netsaint over a SUN have no problem

Thanks
