How to Get Make to Total Up Custom Field from Subtasks and Put the Result in the Parent Task

I have a custom field in my tasks/subtasks for Quantity, and I’m trying to figure out how to get Make to add the data from from this field in the subtasks, and put the sum in the Quantity field of the parent task.

The goal of this is a very basic “warehouse” of items. The parent task is the item’s info with the custom field for quantity on-hand. We’ll add subtasks whenever we send items out and enter something like “-25” in the field; and subtasks when we order more putting “300” in the field.

This is just for a handful of giveaway items we send out, not a e-com retailer or anything that’d need a proper robust inv management.

Open to any ideas, suggestions, or tips.



Welcome to the Make community!

Could you please share screenshots of the module fields and/or filters in question? It would really help other community members to see what you’re looking at.

You can also export the blueprint file to allow others to replicate the issue. At the bottom of the scenario editor, you can click on the three dots to find the Export Blueprint menu item.


Uploading it here will look like this:

Thanks for the reply! I’m no where beyond Watch Tasks and Get Tasks yet, so I haven’t even built the scenario yet. So no screenshots.

I don’t know if Make can tally custom fields in subtasks of ClickUp.
I don’t know if Make can take that tally and put it in the custom field of the parent task.
