MyAssistant Trial Balance does not Balance

I am trying to set up at task in MyAssistant to send out a notification at the end of each week if our Current Period Activity does not balance. I have been told there is a "canned" task for this, but I have not been able to find it. I decided to make it myself by creating a condition "GLM_MASTER__ACCOUNT"."Current_Period_Activity" <> 0, however this only lists the activity for each account for the period. This makes since as that is how the condition is currently written. Is there a way to sum the current period activity? I am currently running Sage 300 and MyAssistant Designer 18.4.

Thank you
