Cell Updates Based on List Options

Hi All,

Hope you guys can help with an issue I can't get my head round.

My spreadsheet contains hundreds and hundreds of criteria neccesary to be completed. I aim to make it more user friendly by using groups to sort the criteria into sections. This was the easy part.

Now, the hard part. (For me at least)

As you can see in the images I made to mock up what I am describing terribly - if any of the criteria are not 'Completed', then the overall group state should say 'Not Done'.

If all criteria are green and 'Completed' then the group state would also be 'Completed' automatically.

I really can't figure out a way to do this. Is there a way?

Thanks in advance!

In cell B8: =IF(COUNTIF(B3:B7,"Completed")=COUNTA(B3:B7),"Completed","Not Completed")

Hope that helps!
