Aggregate Checks incorrect function

[mattjan]

Hi,
I'm using 5.0.
I'm trying to use Aggregate check grpavg but always get Incorrect function expression, below what I've been trying in formula:
grpavg["TestAVG", "perf_counter["\Web Service(_Total)\Current Connections"]", last]
grpavg["TestAVG", "perf_counter["\Web Service(_Total)\Current Connections"]", last]
grpavg["TestAVG", "vm.memory.size[pused]", "last"]
grpavg["TestAVG", "vm.memory.size[pused]", last]
grpavg["TestAVG", vm.memory.size[pused], last]
grpavg["TestAVG",vm.memory.size[pused],last]
Group name is correct (copy paste), item,key is the same for all host group.

I even tried from documentation (I don't have this group but same error):

grpavg["MySQL Servers","system.cpu.load[,avg1]",last]


Presently I do manual calculation to get all average from the hosts and I need to use parseInt(value) because returning string.

Thanks,

My bad, didn't read the documentation properly, type should be Zabbix aggregate instead of calculated item.
