Increment a counter (number field)

[lpb]

@Stephen_Li

is there a way to roll up numbers in subtasks to their parent?

Only as I mentioned with time tracking field as seen here:

Task from Subtask Custom Field Equations - Same as "Column functions"

Note: Not a solution but marked as such to elevate a key reply With time tracking fields, you can get the desired behavior. This shot shows Task 5 expanded; times are entered in subtasks: [image] This shows Task 5 collspased; the subtask time entries are summed in the parent task: [image] Thanks, Larry
