Hello,

I am trying to create a spreadsheet with numerous check boxes.

There are several columns. I want the first checkbox at the top of each
column to "activate" the column when it is checked, and "deactivate" the
column if it is not checked. (In other words, if that column is not checked,
then the work in that column is not done.)

Then, if the checkbox at the top is ticked, I want to be able to select
tasks in each row, that are checked as the task is completed.

I think, I also need to link these checkboxes to cells, as I want to be able
to sort at the end of the day what tasks remain uncompleted (unchecked)

How is this all done?

Thanks!
