Hey,
Taking tasks from planner an in to Excel to with start and due date to make a chart with average time and more....
But when a project is completed without the start and due date filled out the Excel table does not work as it should.
I want to Isolate out the tasks that is missing the start or due date in an Condition
I have tried using the empty function to check if the start and due date was empty.

But it dint seam to work properly because every thing came out empty...
I have also tried saying that the the start and due date needs to contain 20 as in the 20 in 2022 ore 2023

Do any of you have a better way I can isolate the tasks missing the start or due date?
