zabbix aggregate

[sboorbou]

hi.
I have a server named server1
server 1 have a external check trigger with this key
certificado.sh[site,7,15,30,30447]

Now I have server2
in server2 I try to create a item zabbix aggregate with this key:
grpfunc[server1,certificado.sh[site,7,15,30,30447],last]

but I recive a error with "incorrect syntax near ",last]"

What I did wrong ?

to explain,
I want to alert a trigger in server2 when a trigger in server1 become a problem.
