Countifs problem - Using the "OR" function or someting similar

Hi all,

The attached spreadsheet is an example of my problem. In the spreadsheet, in cell F2, I provide the countifs formula that I tried to use to count based on multiple criteria, and I'm having a problem with "Criteria 2" in the formula. For criteria 2, I tried to insert an "OR" argument because I want to count cells that contain two types of text, but it's not working.

Is there a correct way to use the "OR" function here, or is there another way to achieve this?

Thanks so much for any help with this!

Try

=SUM(COUNTIFS(Trials[Trial Number],E2,Trials[Status],{"Not Selected","In Progress"}))
