trigger proc.num[] doesn´t send message

[aram]

Hi, I'm monitoring a process and
have a trigger like:
{SERVERroc.num[process.exe].last(0)}<1

1 - If I stop the process doesn't send me notification error.
2 - When I restart process, yes send me notification like "OK: PROCESS.EXE...."

But I receive "PROBLEM:..." notifications of another triggers like
{SERVER:system.cpu.load[,avg1].last(0)}>6

The {SERVERroc.num[process.exe].last(0)}<1 only send me notification when the state going to "OK".

What´s wrong apart of my bad english?

I think that the problem is solved..... I´m delete this from message body ": {ITEM.VALUE1}" because I think that when it was "0" it have some problem to send message..... I send whit script "sendEmail".

And now work fine.......some body know same thing about this?
