Orion NPM 9.1 SP3 Advanced Alerts Acknowledgement notification

I would like to build an "alert" that let's me know when our techs acknowledge alarms in the system.  I realize I will have to set this up as an additional "alert" but I can't seem to locate the field criteria to use. 

For example:  If Acknowledgement status = 1, send email notification with the following:

Time of Alert is ${DateTime}
Environment is ${Environment}
Node IP Address is ${IP_Address}
Vendor type is ${Vendor}
${Acknowledged}
${AcknowledgedBy}
${AcknowledgedTime}
${Acknowledged}Additional information:

If Acknowledgement status = 0, do nothing.
