Aggregate triggers

[phork]

I have an aggregate item setup and it's working great, but zabbix will not seem to let me setup a trigger on this item. I've tried every reasonable way I know, but it keeps saying it's not correct. Can anyone give me an example of a trigger use a grpsum() item? Thanks!

Found a thread stating this is a bug and should be corrected, so you can ignore this.
