Counting Checkbox fields with a Rollup

[Alyse_Middleton]

I am working on a project/task management setup - I was aiming to have a field that tracks how many tasks are still open on a project.

I have a project table and a task table and the tasks are connected to the projects. The tasks have the ability to be marked as complete with a checkbox. I was trying to figure out how to use a rollup field to count the amount of uncompleted tasks.

You could copy one field where the link is set and paste into new records, or use the drag handle to quickly fill in empty cells with the same value.
