In this item, we have a total of calls made that are added from numbers in the subitems. I’d like to set up an automation that sends a notification to a team member when the count is over x amount.
Looks like you are using the column in the parent that is created automatically when you selected “Show summary in parent” from the subitems. I don’t believe the trigger “When column changes” fires on this (mirror-like) column created in the parent.
Alternatively, the app Rollup Subitems summarizes subitem column data into normalmonday.com columns (in this case a number column). Because this app aggregates to a normal number column you are able to use the automation(s) you prefer.
