Trying to set memory used trigger

[sxm1my]

Hi.
I am trying to add a trigger to alert if the memory percentage is used is greater than 80% and I can't quite figure it out.

Using Zabbix 5.0 and this is for a Windows Server OS.

I am wanting it to alert if the memory percentage is over 80% for 30 mins and so far my codes are not being accepted.

Does anyone have any insight?

I had started with this as I found it but it is not accepting the syntax. - vm.memory.size[pused].avg(30m)}>80


Thanks.

Thanks and yes that was it.
Turns out when I made the initial trigger I had not noticed that I forgot to to change the = to > in the parameters.
